If you have the skills to repair these machines you are too valuable to be a manager a line manager at McDonalds.

A very small number. Most were not. Managers typically don't have the skills (some think they do but don't) - even if they do, running a restaurants needs a lot of effort and spending time fixing a machine is not a good use of your time if you can get someone else to do it (that if is big!)
Gas cars fill even faster. Many EVs don't charge at high speeds, and not all chargers support high speeds even if the car can. Evs do have the advantage of being fully charged before you leave, so trips that can be done on one charge never need to stop. However longer trips have issues.
Don't forget that EV chargers are not nearly as common as gasoline. It is rare that someone needs to plan gas stops on a trip, when the gauge gets down to 1/4 you stop at the next town is the rule most people use (there is variation, those who use 1/8 as the rule sometimes run out of gas, some use 1/2). For EV trips you still have to plan your charging stops, particularly if you are getting off the well traveled path - you can still make most trips but you better how the chargers are working when you get there
they compensate for better economy with smaller tanks in the cars I've seen. Though I'll admit to not knowing all tanks.
For health and safety reasons you should stop, stretch your legs, and take a nap. Unfortunately I know far too many people who are not doing that. Normally they get by with it, but there are many many road deaths every year because of things people normally get by with.
A modern car is far more reliable than anything from the 1970s or before. Sure you could repair those older cars, but also you had to repair those older cars. I'm old enough to remember people bragging about getting 100k miles on a car - they had to check the oil every day, and most days add more. Today a ICE will go 300k miles with minimal maintenance, checking oil is not a common thing for people to do.
if you don't need to, why cry that it can't?
Because I need to drive 300 miles every few months and a car I own that can do that is cheaper than a car that can't and renting something that can for the few times I need it. Rental cars are expensive and most come with per mile charges on top of the daily rate.
Either your drive to the office is unreasonably long, or you are driving much faster than legal. For most roads the legal speed is not that much slower than a bike can go - and you spend a lot of time sitting at stop lights. Which to say an ebike is a reasonable option for a lot of people who refuse to even consider it. Though I don't know your personal situation and so I cannot be sure. (and often the roads you would have to drive on are not safe for bikes which is a real problem)
