A 1938 Cadillac V16 but with shoulder belts all around, disc brakes all around, dual brake system, a decent heater/defroster, air conditioning and stereo AM-FM/satellite/CD/mp3 Bluetooth radio (cleverly hidden in the mobile vault containing my millions in pocket change and hidden under the front seat).
-I want to be able to remotely shut down other cars near me. Now I’m not saying that they are going to full stop immediately, causing the car behind them to crash. They will lose power and gently glide to a stop, a power I’ll use when people piss me off on the road and cut me off or do some other shit. I want to be able to make them sit on the side of the road for an hour thinking about what they’ve done
-A feature that forces people to use their turn signals or they can’t turn. This will be dangerous, I don’t care. If you’re not using your turn signal, you’re not going to change lanes, I don’t care how much of a hurry you’re in. And ideally, you should only be able to turn after the signal’s been active for 2 seconds, not signal and immediately turn. This will cause accidents. I don’t care. And in case they have it in their mind to keep the signal on permanently so they can turn any time, the signal automatically stop working after about 10 seconds
-A mass area effect that can control all the cars near me and make them move a certain way. For times when I want everyone to back up and stop trying to squeeze forward in an intersection and gridlock the damn thing
-You know what? Let’s just go ahead and make it possible for me to remotely control any car I see. I’ll use it only for good. Run a red light? Sorry, your car’s going dead for an hour. Stop at an intersection because you couldn’t wait until the next light and had to? Have fun at the next parking lot. Refuse to let someone in even though traffic’s stopped? Good luck getting to wherever you’re going today because I’m locking your car’s speed at 25mph for 24 hours
-I also want to be able to hijack any car’s radio so I can talk to them and yell at them for being back drivers, but I don’t want them to be able to talk to me because I don’t want to hear their excuses. So for any of the violations above, not only will I mess with their car, I’m going to tell them why I did it and why they are assholes

I understand I can modify a vehicle somewhat to improve the ride. When I used my Diesel F250 for towing, I had the springs modified quite a bit to improve the ride, since I didn’t carry large weights in it. Removing the overloads, and replacing the primary rear leaf(s), combined with the truck’s 7K lb weight made for a pretty good ride. It could only carry 6-800 lbs, but the trailer’s weight distributing springs made that acceptable.
My objection is about passenger cars. I don’t understand why I must modify them to get a decent (to me) ride. I’m probably in the minority as I don’t care a whit for “handling” or “road feel” beyond that necessary for safety. I’m not racing them. My old duece-and-a-quarter could be steered with a single finger on the wheel, and I could back over a land mine without noticing. And it was quiet. I got almost no road noise, and frankly could be driving over gravel, soda cans, or the odd Camry without hearing a thing.
That’s how a long distance road vehicle should be.

Intercity travel may be the first aspect of driverless technology to be widely utilized. Travel at night and arrive at another city 700 miles away in time for breakfast. Why waste awake time on the interstate?
My needs are pretty simple, as would my dream car be…
No nannyware of any kind, traction/stability/yaw “control”, if it takes control away from the driver as a “safety” system, it has no place on my dream car
No electronics in critical systems, no EDR “black box” no onstar/sync etc…
High performance mechanical gear, performance optimized suspension, brakes, steering, it must put a premium on handling
Manual transmission, that goes without saying…
Basically, I’d want a Ferrari F-40 or McLaren F1…
Take the electronics out of the critical systems of those two cars and you are left with two very large and pretty paperweights.
You could still sit in them and yell vroom, vroom at the top of your lungs.
Ok to clarify, I merely meant no black box tattletale box, onstar and the like, if the electronics are necessary for the engine to function, then they stay
Oh and I also want a second vehicle, a simple mechanical diesel vehicle, something EMP proof, just because the old workhorse mechanical diesels are cool, have triple fuel tanks, petro-diesel, waste veggie oil, and straight veggie oil
