Plug-in vehicles or electric vehicles are safer than combustion engine vehicles in regard to fire risk and noxious fumes. Because these vehicles do not burn fossil fuels, the risk of a fire is minimal in a crash.
Since automakers come out with new models and trim lines every year, these new automobiles must be somehow superior to their previous generations. In some cases, this idea may have some merit, but in many cases, it is just not the case.
