Sounds real stupid to do if your intent for the car is autocross and hitting the tail of the dragon and generally sporty driving. Why cheap out on brakes?
I say this as someone who has A. Driven the tail of the dragon and B. Owns multiple vehicles with manual brakes and manual steering
How would your car know you’re alcohol impaired? What methodology will the car use to determine this? The least invasive one I can think of would be poor driving, weaving in and out of lanes, etc. So it must be monitoring that (or something) and arbitrarily decide that you’re impaired, and shut the car down.
Next they’ll take speeding, I’m sure.
