Classic Mopar Use ????

is anybody concerned about the lack of safety with these cars on long drives or busy highways?
Lack of safety?
When these cars were built, we had expressways and 75 mph speed limits. Long drives were no different then than they are now, just maybe busier and with more inattentive idiots on the road- but that has nothing to do with the cars themselves. After '66 they had collapsible steering columns and available 3 pt. harnesses; and after '73 (?) had door I beams. Other stuff I'm not thinking of right now.
They're NOT loaded down with 12 inch videotainment distraction systems, rub-your-tummy-and-stomp-your-foot to change the heater controls, power door locks/mirror controls/pedal adjustments/etc. that stop working as soon as the car is out of warranty, and a plethora of other cr*p that becomes a liability as soon as it starts to act up...
Not to mention, both my '66 and '75 get better mileage than my '08 Grand Cherokee...
Honestly, I'm just as, or more; nervous taking a newer car on an extended trip as my classic. At least I stand a better than average chance of fixing whatever basic systems it has while on the road, whereas a late model is "call a flatbed and rent a car" time.
