Sat on my grandfathers lap at maybe 5, and drove the last block home, at maybe 5MPH I was king of the world. Of course now, thanks to air bags, putting your kid in front of you like that could kill them if it went off.
Sis sat on Pop's lap and drove the car. I shifted the gears from the passenger seat, and Pop worked the pedals. No one wore a seat belt and there was almost always an empty Miller Pony rolling around on the dash or floor. That little Triumph Spitfire could boogie too.
