If you are of a certain age, have the ready cash and if new cars are truly safer than old cars, then do society a favor and buy the new car. It’s cheaper for society to make a new car that keeps the aging driver, passengers and other drivers and pedestrians safe, than to pay to fix even one broken old person.
I’ve got a 2025 sedan with all the newest safety features, and what you lose in visibility you more than gain in general situational awareness, especially with aging eyes, ears, etc.. Managing display and alarm complexities is the challenge, though, since the aging population also have issues there. A driving training simulator at the dealership for these new sedans for the elderly would be a big help, since many of the safety options are only active in a vehicle under motion. The temptation for the aged is just to shut these confusing options off as too complex, thus losing the safety advantage.
