The car actually detects faults and tells you what to do ?
well show me the gas car that does that when a faults causes it to catch fire... and unlike this, they usually burn quickly into the passenger compartments, and there's been a lot of cases where people discover smoke coming from the engine area, and stop the care, and they barely make it out of the car with their family before the whole passenger area is engulfed.
Right? I had a spark plug break in my car, the engine was shooting gas at the exhaust manifold, it was not far off from catching on fire, and outside of the fact that the car ran like garbage (as one would expect when your car has become some sort of gasoline pump machine instead of an internal combustion engine), there was no notification to my impending doom. Didn't even get a check engine light, even though I've got to believe some of the exhaust sensors were out of whack at that point.
Also, has everyone forgotten all of those Explorers that caught on fire by themselves in the night time in people's garages, burning down their entire house? They didn't call them Exploders for no reason. Sure, gasoline and electricity both have their risks, but if I had to chose one to handle every day and stick in a box near me as I fly around at 60+ mph, I'll take the electricity, thanks. At the very least, it smells better.
