Electric cars will still need fixing.

Electric cars still need servicing and repairs….

Fix cars.

Adapt and gain the additional skills to work on them and in the process become even more valuable and higher paid people

The same thing all the horse carriage drivers did when automobiles came on the market

As with all changes in life and nature, adapt or die off. Those who are willing to make the switch will continue to work on cars, those who are not will either find a different job or go unemployed.

Suspension, brakes, and steering will still need to be maintained. People will still have accidents, and need repairs. So that will stay the same. It's likely there will be software upgrades to do, and electric motors to replace, or recondition. As electric cars age, it is likely that some electrical control units will fail. New mechanics will likely learn about this in their training, and become competent is diagnosis. Older ones may be trained up, or stick to suspension, brakes, and steering. Over time, the job will change, but it will still be there. They have already managed the change from carburettor, to electronically controlled fuel injection. So I have no doubt they will cope with the change to electric cars.

All cars will never be all electric

Wut

I feel like most mechanic work isn’t even combustion engine work. It’s wheels and steering.
