Drivers in Pennsylvania may or may not have advanced driver assistance systems in their cars, but they should at least understand the benefits that they bring. General Motors has a study out based on actual crash data rather than simulations and other tests, and the results are positive. ADAS can prevent crashes, but many features are not as effective when considered alone.

For example, rear-view cameras by themselves can reduce the number of back-up crashes by 21%. Rear park assist by itself brings the number down by 38%. When these two are combined with rear cross-traffic alert, the number of accidents is more than halved. Lastly, add reverse automatic emergency braking to the three features, and cars see 81% fewer back-up crashes.

Rear-end crash numbers decline by 21% with forward collision warning and by 46% when that is combined with forward AEB. The study also found that lane-departure crashes become 20% less likely with lane keep assist and lane departure warning while lane-change crashes are reduced by 26% with lane change alert and blind-spot monitors.

In a similar study that went beyond GM vehicles, the non-profit Insurance Institute for Highway Safety found that AEB halves the number of rear-end collisions. Rear AEB with sensors and cameras decreases crash numbers by 78%.

Without ADAS, many drivers might be negligent behind the wheel. If negligence leads to a car crash, and if that crash leads to a serious injury, drivers may be held responsible. This is a no-fault state, so only those who incur a serious injury or disability can file a third-party insurance claim. Victims who believe they are eligible may want to see a lawyer. If hired, the lawyer may have investigators gather proof against the defendant and medical experts measure the extent of injuries.
