If you are safely hurtling along an Interstate at 70 mph, in a car whose systems required literally millions of hours of engineering, on a road surface that was also heavily engineered and painstakingly built by hundreds of workers using millions of dollars worth of large equipment... then congratulations, you've already ceded control of life-critical operations to numerous big, opaque corporations.
You're trusting your life to GM, Toyota, and the manufacturers of all the cars around you, that they won't spin out of control and kill you. You're trusting the road designers and government regulators that the surface won't suddenly buckle or turn. You're also trusting all your fellow bozos on the road not to be drunk, sleepy, texting or spilling coffee in their laps. Looking at the odds of what causes road deaths, I'm not that unhappy about extending further trust of my life to the relatively capable hands of auto company engineers.
