CMT evaluation finds variations in driver threat amongst EV, ICE automobiles

Drivers of electrical automobiles (EVs) usually tend to interact in dangerous behaviors like rushing and exhausting acceleration, however battery vary and local weather impact miles pushed, in keeping with an evaluation printed by Cambridge Cell Telematics (CMT).

Insights like these are “only a begin to understanding an electrified future,” CMT, the world’s largest telematics service supplier, mentioned within the evaluation, “Do Electrical Automobiles Make Drivers Safer or Riskier?”. It mentioned the information can be utilized to section threat publicity, driver conduct, and claims for ICE automobiles, hybrids, and EVs.

“As main auto producers and plenty of governments announce aggressive targets for complete fleet electrification, the work of understanding EV threat solely grows in significance,” CMT mentioned.

EVs “show distinctive threat elements which can be distinct from inside combustion engines (ICE) automobiles,” the report mentioned. “The analysis highlights quite a lot of key variations throughout car varieties. For instance, we discovered that Tesla drivers exhibit acceleration dangers that vary from 346% to 406% greater than the common ICE car driver. These Tesla drivers additionally had 76% extra cornering threat. On common, they have been 35% much less distracted by their smartphones than ICE car drivers,” the report mentioned.

CMT mentioned one if its findings is {that a} driver’s threat profile can change, relying on what sort of car they’re driving.

The corporate used its information to analysis drivers who personal and drive multiple car. It discovered that Tesla drivers are 48% much less more likely to crash their Tesla than their internal-combustion engine (ICE) car, whereas Porsche drivers have been 55% extra more likely to crash their Porsche than their different ICE car. Porsches “give us comparability to Teslas as a result of they’re a high-performance car at a premium worth level,” the report mentioned.

The evaluation additionally discovered that drivers are 9% much less more likely to velocity of their Teslas than of their ICE automobiles, and are 21% much less distracted by their cellphone — “presumably as a result of they’re interacting with the in-car show as an alternative.”

The outcomes are much like these from the Freeway Loss Knowledge Institute (HLDI) exhibiting that the Tesla Mannequin 3 has a decrease frequency of claims in comparison with comparable high-end luxurious automobiles. “Throughout all vehicles, their analysis suggests Teslas have greater crash frequency, severity, and complete loss prices,” the report says.

Within the multi-vehicle comparability between hybrids and ICE automobiles, hybrids underneath $75,000 had a 98% greater crash threat, whereas hybrids over $75,000 had a ten% decrease threat.

One of the vital predictive elements of crash consequence, CMT mentioned, is threat publicity. Usually, the extra an individual drives, the upper their crash threat is. Via information collected by telematics merchandise Superior Danger, DriveWell Auto, DriveWell Tag, DriveWell SDK, and DriveScape, it was in a position to focus in on variations of threat exhibited throughout totally different lengths of journeys.

CMT mentioned its Superior Danger expertise “supplies subtle capabilities to know what results in automobile crashes, figuring out the incentives that cut back threat with extra precision.”

The evaluation additionally sorted information by car sort. Teslas and hybrid automobiles confirmed an analogous threat publicity, each in distance pushed and journey period, whereas the common journey for a compact EV was 26% shorter in distance and 10% shorter in time than for ICE automobiles, giving them a decrease threat publicity.

Climate has an impact on EV threat publicity, too. In contrast with ICE automobiles, there’s a 38% chance that Teslas are used for journeys over 100 miles throughout the summer time in heat climates, and a 52% likelihood in chilly climates. The evaluation discovered a wider distinction for compact EVs, that are 70% extra more likely to be taken on lengthy journeys in the summertime in chilly areas, and 111% extra probably in heat areas.

“EV utilization could be impacted because of temperature and capability as a result of many EV fashions can’t make longer journeys with out stops,” the report mentioned. “As battery expertise advances, and ranges improve, this particular issue may evolve for a lot of EVs. It additionally might not maintain true for EVs with longer ranges immediately, such because the Mercedes EQS (453 miles) or the Ford Mustang Mach-E (379 miles).”

CMT mentioned its information means that gas costs have a direct impact on driving patterns. “As gasoline costs have elevated since February 2022, individuals who drive each an ICE car and a Tesla started driving their Tesla extra continuously. In January 2021, 63% of their journeys have been of their Tesla. In January 2022, that quantity held regular at 64%. However since February 2022, Tesla journeys have elevated to 70% of all journeys,” the evaluation mentioned. The graph above exhibits the variation between the every day complete mileage (normalized by the variety of customers who took a visit that day) in 2022 vs. 2021 for Teslas.

On the identical time, as gasoline costs hit $5 a gallon, journeys in ICE automobiles dropped over 8% in comparison with 2021, the evaluation mentioned.

EVs, and Teslas particularly, are identified for his or her capability to speed up shortly, significantly from a standstill. This makes it unsurprising that drivers of compact EVs had an acceleration threat practically 3 occasions that of ICE car drivers, whereas Tesla drivers had a threat 4.5 occasions greater. The evaluation additionally discovered discovered a distinction amongst Tesla fashions, with the acceleration threat for the Mannequin 3, for instance, 5 occasions greater than ICE automobiles.

“These findings may recommend that EVs are riskier — if we restrict the evaluation to acceleration threat,” CMT mentioned. “Nonetheless, the total image is extra nuanced. Harsh braking threat in EVs is much like ICE automobiles. Hybrids have 8% much less exhausting braking. Compact EVs have 23% extra exhausting braking. Teslas are nearly similar. Cornering threat can be comparable amongst car varieties.”

There was much less variation on rushing threat, one other widespread reason for claims. Tesla drivers velocity 7% greater than ICE car drivers, CMT mentioned, whereas hybrids and compact EVs velocity much less — 18% much less and 24% much less, respectively.

“We discover these outcomes intriguing,” the report concludes. “Our hope is that this high-level evaluation will spur further analysis into this matter throughout tutorial, non-governmental organizations, and street security professionals to assist higher perceive the evolving security dynamics of ICE, hybrid, and electrical automobiles.”

The analysis was offered on the Insurance coverage Institute of Freeway Security — Freeway Loss Knowledge Institute (IIHS-HLDI) Car Analysis Heart as a part of the current “Charging into an Electrified Future” convention, an insurer-focused occasion on the impression of electrification on threat evaluation. That is CMT’s first publication on EV threat.
