If you want to lament a general lack of awareness and progressive education, then I'm fully on board. Perhaps we should require operators to pass an additional driver test to be legally permitted to supervise any L2+ system from any manufacturer. No BlueCruise or SuperCruise unless you've got the extra marking on your license.
But as far as "consent" is concerned, if you wish to use the public roads, consent necessarily means accepting the roads as a commons. This means, at minimum, accepting the presence of anything the relevant government authority deems legal.
I'm not really talking about formal education here.

All that means if you have enough money you can put whatever death machines on the road you want. I don't think that's a good way to manage a road network, and will not ultimately lead to greater safety for all.
