To me an old car that might leave me stranded is a bigger safety issue than a lot of the new car safety features

Is there a part of town where you'd rather not be stranded? Trust me, life being as it is, that's probably where it will break down and leave you stranded.
Also an old car that is breaking all the time could *cause* an accident, because it may unexpectedly break and not perform as designed in an emergency situation.
Bear in mind that I am a female with zero interest in proving my chops as an auto mechanic, great interest in living to an old age, and I stick to buying new Toyotas for reliability. That said, here's my opinion:
Driving an extremely high mileage car says nothing whatsoever about you except;
1) you have to get your car running again at unpredictable, unexpected times when there actually might be something else you want or need to do, and
2) you think that's perfectly OK. And also,
3) you do not care about the safety of yourself, your passengers, or anyone else on the road. You'd as soon they all die.
It's not lack of new safety equipment that resulted in the New Orleans canals being full of old junker cars (often containing the bones of their driver). It doesn't matter how many sensors your car has if a wheel falls off or you have other catastrophic breakage in the middle of a turn.
As for the new safety equipment/standards, don't need them, don't want them, and I think often they encourage irresponsible driving. By that I mean that I completely agree with Winemaker when he said
Am I that lazy to not turn my head, or use a rear view mirror, and rely on a camera? Do I need lane wandering lights and alarms? Does my new truck really have to slow down automatically when the vehicle in front of me is not going the same rate of speed as me? I'm the licensed operator of the vehicle, not the software and sensors.
Keep your high mileage car if you need a project to feel happy, but don't drive it regularly; buy a new car for that.
Well, unless your financial situation is such that you cannot afford to spend more than about $15K/year on all expenses, and have no possibility of improved circumstances in the future. Even then I'd recommend selling your high mileage car and buying a bicycle.
