Vehicle classes Automobiles and trucks are the leading categories in terms of motor vehicle sales in the United States, accounting for roughly ** percent of all registrations. Motorcycles and buses comprise the remaining categories, with buses accounting for a miniscule **** percent of registrations. In terms of sales, light trucks were the most popular category in 2024 with retail sales of nearly **** million units. Leading state California recorded around **** million registrations of automobiles and trucks, having a resident population of just under ** million people. California is the largest market for car registration. The state is known for progressive state legislation that promotes the manufacturing and sale of electric vehicles.

In 2023, California had the most automobile registrations: almost 13.2 million such vehicles were registered in the most populous U.S. federal state. California also had the highest number of registered motor vehicles overall: nearly 30.4 million registrations.

Vehicle population is updated annually, each April, to reflect the number of vehicles “on the road” during the previous calendar year. Vehicle population counts vehicles whose registration is either current or less than 35 days expired. Sales are higher than population because of vehicle retirements, accidents, owners moving out of state, or other reasons.

In-Vehicle Data Privacy Engine Market Outlook

According to our latest research, the Global In-Vehicle Data Privacy Engine market size was valued at $1.2 billion in 2024 and is projected to reach $9.8 billion by 2033, expanding at a remarkable CAGR of 26.5% during 2024–2033. The rapid proliferation of connected and autonomous vehicles, coupled with increasing regulatory scrutiny on data privacy, is a major factor driving the robust growth of this market globally. As vehicles generate and transmit vast volumes of sensitive data, automotive manufacturers and service providers are under mounting pressure to deploy advanced in-vehicle data privacy engines to ensure compliance, safeguard user information, and maintain consumer trust. This surging demand is further fueled by the exponential growth in digital mobility solutions and the integration of sophisticated infotainment and telematics systems, positioning data privacy engines as a critical component of the modern automotive ecosystem.

Regional Outlook

North America currently commands the largest share of the global in-vehicle data privacy engine market, accounting for approximately 38% of total market value in 2024. This dominance is primarily attributed to the region’s mature automotive industry, widespread adoption of connected vehicle technologies, and the presence of stringent data privacy regulations such as the California Consumer Privacy Act (CCPA) and other state-level mandates. Leading automotive OEMs and technology giants in the United States and Canada have made significant investments in developing robust data protection frameworks, further propelling the adoption of in-vehicle data privacy engines. Additionally, North America benefits from a highly developed digital infrastructure and a tech-savvy consumer base, which collectively foster rapid integration of advanced data privacy solutions within passenger and commercial vehicle fleets.

Asia Pacific is emerging as the fastest-growing region in the in-vehicle data privacy engine market, projected to register a stellar CAGR of 32.1% between 2024 and 2033. This growth is largely driven by the booming automotive sector in countries such as China, Japan, South Korea, and India, where the adoption of connected and electric vehicles is accelerating at an unprecedented pace. Governments in the region are increasingly enacting data protection laws and investing in digital infrastructure, which is compelling automotive OEMs and mobility service providers to prioritize data privacy solutions. Strategic partnerships between local automakers and global technology firms, as well as rising consumer awareness about data security, are further catalyzing investments in privacy engine deployments across both passenger and commercial vehicle segments in Asia Pacific.

In contrast, emerging economies in Latin America, the Middle East, and Africa are witnessing a gradual uptake of in-vehicle data privacy engines, primarily hindered by challenges such as limited regulatory frameworks, lower digital literacy, and slower adoption of advanced vehicle technologies. However, as these markets continue to urbanize and digitize, there is a growing recognition of the importance of data privacy in the context of smart mobility and fleet management solutions. Localized demand is beginning to materialize, particularly among fleet operators and mobility service providers seeking to differentiate themselves through enhanced data security offerings. Policy reforms and international collaborations aimed at harmonizing data protection standards are expected to gradually unlock new growth opportunities in these regions, albeit at a more measured pace compared to developed markets.

Report Scope

This research tests an implicit assumption on investment in plug-in electric vehicle (PEV) charging infrastructure: people who are not already interested in PEVs will see public PEV charging and become interested in PEVs. Data from a survey of car-owning households in California are combined with data on public PEV charging and PEV registrations to estimate a structural equation model of the extent to which participants have considered acquiring a battery electric vehicle (BEV) or plug-in hybrid electric vehicle (PHEV), and whether participants report seeing PEV charging. The model controls for socio-economic and demographic measures and participants’ awareness, knowledge, and assessments of PEVs, and the known correlation between PEV registrations and public charging locations. Using logistic ordinal regression we also assess whether charger density near workplaces affects the results. All results contradict the assumption that people will see charging infrastructure and that more charging—rather than more people seeing charging—means more people will consider purchasing a BEV or PHEV. Rather, prior interest and positive assessments of PEVs, allow people to see PEV charging. In short, interest in PEVs is a prerequisite to people seeing PEV charging. Methods We use data from car-owning households (all cars, not just PEVs) from a survey completed in 2021 by nearly 3,000 respondents across California. These data are supplemented by data on the contemporaneous (with the household survey) counts of charging locations and PEV registrations in survey participants’ home zip codes. The analysis also controls for density of PEVs in the participants’ home zip codes as there is geographic correlation between PEVs and PEV charging infrastructure. Further, the analysis includes whether participants see PEV charging. The survey instrument also measured consumer awareness, knowledge, assessments, and consideration of PEVs. The sample was recruited by a professional survey firm. Participants were recruited from panels of people maintained by such firms for the express purpose of participating in research. Participants are typically screened based on criteria relevant to each study to which they are invited. Firms providing this service typically reward participation based on how many studies a person completes and the time and effort required to do so. Because all recruiting was done by the vendor and because these firms typically maintain cooperative relationships with each other allowing them to recruit from each other’s panels, the number of initial invitations to the pre-screening questionnaire for this study is unknown. Thus, a traditional response rate cannot be calculated. What is known is the number of people who screened into this study’s questionnaire and how many completed it. The completion rate was in the low-70 percentages. Participants were screened into this study via a pre-questionnaire establishing eligibility, determined primarily by respondent age (for reasons of informed consent and for quota sampling), respondent sex, household vehicle ownership (for basic eligibility), household income, and residential zip code. Quotas for age, sex, and income were set to match regional distributions within California for car-owning households. The analysis here is for the state.

In 2023, California boasted the largest all electric vehicle fleet, at approximately *** million units. This volume dwarfed registrations in all other states, with second-in-the-ranking Florida recording some ******* battery electric vehicles in use on its roads.
