Everything's relative. People a century ago would probably have felt uncomfortable at the idea of DIYing a multi ton vehicle being accelerated by a extremely high power pistons pounding up and down thanks to creating a controlled explosion inside a tight little box, that you can then hop in and cruise around at 80MPH+. And indeed if something goes critically wrong, you're dead. We just work to reduce the number of ways that things can go critically wrong.
I can't find the details now bit in the early 19th century an MP introduced a bill to parliament to make it illegal for trains to go over 30mph because in his opinion it would be impossible to breath at that speed.
