value/dollar in terms of what you can use a car for (transportation, carrying stuff, time spent driving versus time spend filling up)
Cheapest EV is 30k right now - nissan leaf.
For that much, you can get a Prius Prime , which can be driven like an EV to work and back, charge at home, and when you go on a long trip, you don't have to worry about finding charging stations
You can also get a hybrid Ford Maverick. While you can't charge it at home, It gets 500 miles tank of gas, a full bed for carrying stuff, outlets in the bed for tools or camping, and offroad capability, and again, can fill it up at any gas station.
If Nissan leaf was like 100 mile range, basic vehicle for $10k, then it would be a different story. But right now, paying the same for way less capability doesn't make sense.
So you don't have a quantitative measure of utility of which you can precisely determine a "half", you have a vague idea of "value" on which you want to place a veneer of quantitative analysis that will last exactly until someone calls you on it. That's not specific.
Lets say utility is time that you can spend driving the car versus it sitting still, multiplied by amount of weight you can carry, divided by cost of vehicle.
Let's say that every unit of time spent driving a vehicle is of equal utility for every person, and that the utility scales linearly with the absolute length of a given stretch of driving or time between. Let's say everyone uses their car to go basically the same distances to the same kinds of places carrying the same cargo and passengers, with basically the same costs for needing an alternative. Let's also say that cows are frictonless spheres in a vacuum.
Or we could just not pretend that "utility" is a concept that can be applied uniformly across all car-shaper objects.
