It seems to me that people should spend their first few hours of driving lessons in a simulator, instead of on the road:
-Less scary for learners.
-Less inconvenient for other road users.
-Safer for everyone.
-Probably cheaper for the driving school in the long run.
-Lower carbon emissions.
But this doesn't seem to be a thing, in the UK at least. Why not? Surely it can't be that expensive to create a simple car simulator with steering wheel, gears and pedals. And the graphics could be pretty basic by modern game standards.
When you're first learning to drive, think about how cautious you were when you put your car out of park for the first time. Chances are you barely touched the gas and inched forward while you discovered how much pressure it takes to accelerate or stop. You probably treated it like you were stepping foot on an alien world for the first time. A mode in your brain flipped that said "we're not screwing around here, this is actually happening".
I think simulators work for specialized things like flying because the stakes are high for tiny mistakes. If you flip the wrong switch or do something slightly wrong you might not only die but you'll also destroy potentially months or years of research and tens of millions of dollars.
Driving a car on the regular road has a different type of stakes. You can kill yourself and hundreds of others just by driving a few hundred feet in some places but the act of driving itself is much more forgiving for tiny mistakes.
