You're pretty much done if the life support systems on a plane fail and you're pretty much done if your car has a massive failure while you're doing 70MPH. I can't imagine it being statistically more dangerous than driving.
Driving seems to get a special exemption in the public consciousness. Trains and planes are already much, much safer than driving, but they're still required to add additional redundant safety features, and there's still outcry when one crashes.
