You seem to have a very strange view of what happens to batteries.
AIUI, their performance decays gradually, but over a realistic car lifetime (say 1000 charges, 200,000 miles) they're not going to be "shot" but perhaps lose a % of range.
Whereas the complicated drive trains of ICE cars have all sorts of expensive failure modes.
Happy to see any facts that contradict this view.
No I don’t have a very strange view of what happens to either lead acid or Li-ion batteries, you can expect between 500 to 1000 full charges from a Li-ion battery, now if that EV has been a company car doing high mileage with let’s say a range of 180 miles real world driving as an average through winter & summer with heating or a/c on as required , along with lighting and in car entertainment being used, at 100,000 miles it’s had 555 full charges, so it will have started to degrade in available range, so consequently it has to be recharged more often, at lets say 4 years old when the car is returned to lease company and ends up on the used car forecourt you can see at best it’s used over half it’s expected life span, possibly even more, so as the range becomes less and less your using up the remaining lifespan even quicker, now as for complicated drive train on ICE’s , EV’s also have a reduction gear between the traction motor and the wheels, which can and do break, the car, particularly in the 4WD variants won’t have a differential, instead they rely on electronics to slow the drive to the inside wheel when cornering, the speed sensors and control ECU’s can fail, speed sensor bearings in traction motors can fail, resulting in the vehicle driving slowly and feeling like it’s literally shaking itself to bits, as can heat sensors, so the car thinks the motor is overheating, the A/C chopper box (the bit that turns DC battery power to A/C) can fail, generally losing one of the three phases to the motor is most common, it’s not fault free running electrical vehicles, all of the above will lead to huge repair bills, both in time consuming labour and expensive replacement parts
