They are so big and it seems like so much could go wrong yet they are statistically extremely successful.

Commercial air travel is one of the most highly regulated industries in the world.

Imagine if it was the same for driving:

– Every new model of car is put through years of testing by a government agency to ensure safety

– Every crash is investigated by that agency and new traffic laws or design changes are mandated every time.

– Every time you bought a new car, you had to study the differences and then retake your drivers test to prove you can drive the new model.

– Every quarter, you had to log simulator time on that car, practicing scenarios that could go wrong. If you fail, you can’t drive until you pass.

– You had a team of mechanics that checked the car out every time you drove it. If there was something off, you didn’t drive until they signed off.

– You logged the mileage on every critical part and replaced them before the broke.

– You had a team of people feeding you real time traffic and weather information so you could take the safest route.

– If the weather is too bad, all driving is canceled until it clears up.

– You had someone in the passenger seat with the exact same training that could take over at a moments notice.

– Every other driver on the road was doing the _exact_ same thing.

If driving had all that, we’d see _far_ fewer crashes.
