> I realize commerical aviation is a bit of an exception If flying in free air had the same number of variables as driving on oddly shaped roads filled with oddly shaped vehicles and obstacles and the occasional people crossing where they shouldn't, we'd have an air crash every hour. A flock of pigeons usually isn't fatal for an airplane engine, now imagine flying surrounded by people testing their new jet backpack. I'm 100% convinced we'll send someone to Mars a lot before we'll have safe self driving vehicles.
