Several in the 1,000 to 1,500 HP range, including full body tube chassis cars with 5 speed manuals.

Also driven a couple of over 700 horsepower trucks with multiple transmissions, etc.
And a few high HP boats.
More pertinent to this part of the discussion, I have a great deal of experience in the ADAS/ICC and other alphabet driving systems, with knowledge of their design, inner workings, and what they are and are not capable of, as well as what corners are cut.
Apparently, the majority of humans are quite stupid and lazy, and perfectly willing to hand over control of large portions of their lives to machines. Of course, they hand their minds to college professors and the media, without a second thought about what is being put into it.
