Moving parts wear out due to friction. The electronic parts you listed are not moving parts and rarely fail. I would know, as an automotive technician they come to me when they break.
If you really were an engineer, you would know about minimizing points of failure. And you would be able to recognize gas vehicles have exponentially more points of failure due to the amount of moving parts and sealing surfaces and combustion temperatures.
It’s easy to claim you’re an engineer on the internet. But you’re definitely not talking like an engineer.
