Some of the stuff you learned from your driving manual and your parents about driving doesn't apply anymore, and some are flat out wrong.  Mostly to do with advances in technology! Vehicles have gotten more upgrades than you could imagine.  Here are the top four on the list from one of my favorite websites for cool stuff Thrillist.
1.  Driving with your hands at 10 and 2 made sense in the 1950's. Most of the affordable cars didn't have power steering.  Now that you can turn the wheel with your pinky finger, grip is not so important.  Airbags can break wrists and thumbs, so for safety sake you should have hands at 8 and 4 these days.

2.  Pumping your brakes to keep them from locking up... NO.  In the 1950's, no such thing as antilock braking systems. That's what the brake is pulsing is for. I remember my father asking me why it was that when he smashed the brakes down "it felt like ice crunching around under the pedal".

3.  If your car won't start, forget about pumping the gas.  When cars had carburetors, that was useful to get more gas into the combustion chamber. Now with fuel-injection, if you smash your foot through the accelerator the car shuts the gas off to prevent engine from flooding.  I had a truck once that was flooding and wouldn't start. So I mashed the gas pedal to the floor to shut the fuel pump off and it would start.

4.  Don't hold the brakes down over a speed bump.  I'm not saying fly over them at 60 mph either. Slow down right before you hit the speed bump. Hitting the brakes while you're going over makes your vehicle lunge forward, so it's harder on your suspension and makes you bounce more.
