There will always be a car culture. I've used facebook to find different GTG car events and can honestly say it is easier to find a good gathering of people at any moment than it was in the early 1990's. Back then, Sunday nights in Philly was the highlight of the week. Anything in between might be a cruise night or a packing lot of a few high school die hard car guys. Even around my non-car guy high school buddies they always liked being in my car when we would meet people. They may have had licences, but didn't "get it" like we do. I didn't hold it against them (much

) Now, there is something happening every night and day. Maybe there was before and I'm just more aware of it.
My kids only being 6 & 8 years old know that I am enthusiastic for them to be driving as early as possible and they seem to be excited too. Maybe there will be a decline in the # of friends driving. Heck, in 10 years some will have self driving cars, for sure. That's a whole other can-o-worms.
In the end, I'm satisfied with the car culture I've observed of people 16-21 years old. I feel things are alive and well.
