It's a crazy time to be alive. Never saw this coming

I think often about how I was talked out of high self employment high local demand trades when planning my career. If I could talk to my younger self I think I would advise electrician and start your own business ASAP. If I had realized cars would become computers overnight I might have picked mechanic, harder to start your own shop than electrician though.
I was in automotive tech (older vehicles) for the past 7 years. Shops that had found good labor prior to 2020 are doing great. Repair only though. When modifying the EPA poses a huge risk to your business and personal well being. That's mostly why I'm out of automotive.
All my vehicles are modified yet I have not added anything to make more power. (arguable, I did an intercooler on my 3.5 ecoboost f150 to reduce temps while towing not to make power)
Modern cars are plenty powerful, you'll get more out of tires, brakes, and suspension than 10hp from an arguably legal bolt on power adder.
In my field (diesel) we were making 100hp over stock just in a calibration change. But yes, some modern vehicles make more than double the torque over what they did a little over a decade ago.
