I was watching the Leave it to Beaver marathon on WMEU-CA (local low power TV station in Chicago) and Lumpy (a year older than Wally and Eddie) offers to drive them to the track meet. (Eddie is the team manager and Lumpy and Wally are competing).
“The Lump’s” car breaks down and they ask Ward if Lumpy can drive his car to the track meet. Ward let’s them with predictable hilarious results.
So my question is would you let your teenage son’s friend drive your car. (In this case Wally and Eddie are 15 while Lumpy is 16 and has his license).
No just ‘no’, but ‘hell, no!’
I’ll take it a step further and say I wouldn’t let anyone drive my car when I wasn’t familiar with their driving style/responsibility as a driver/etc., no matter how old they were.
Not just no, but hell no. My insurance is horrible enough as it is.
No. My insurance covers anyone with my permission and a local drivers license and over the age of 25 to drive my car. In fact the brakes are sharp and the steering is a challenge - I’m not sure if I should let myself drive it too often. My insurance is really low and it’s staying that way thanks.
I’ve let students drive my car on a couple occasions, which is sorta the same thing, but only to park it, and even that very rarely.
What’s weirder to me is to ride in a car with a teen driving.
Which one?
My kids have had some friends who were good drivers, and some whom I wouldn’t let drive my skateboard.
Another thing about the Beaver days is that there were fewer cars on the road. Seems to me that driving was less of a hazard back then.
Just in case no one else says it, not just no but HELL NO! 
My brother actually let a friend drive our parents’ car. Said friend ended up driving it off the road and flipping it in a ditch. No insurance.
Emphatically, expletively NO.
I wouldn’t let my teenage friends drive my (parents’) car when I was a teenager myself. I drove this little Plymouth station wagon that was a stick shift, and it was really tricky to start and drive in low gear. When my best friend begged to drive it around a parking lot (she was in driver’s ed), I told her she could drive it if she could start it–knowing full well she would never be able to manage it.
That said, it would depend on the kid–but my first inclination is to say no. Then I think of some of the really great teenagers I know, and think maybe I’d let a few of them do it. (And anyway, most of them drive their parents’ cars, which are much nicer than mine…)
