There's no need to be sarcastic; I want you to be more persuasive because I completely agree with you that it is unreasonable to expect private citizens to be able to do things like: notice a full-grown man in rollerblades on the side of a highway, or notice you have collided with a rollerblader, or safely overtake a rollerblader, or notice that the rollerblader is no longer visible and is instead dying on the side of the road. People can't do this if they are 32 or 82 -- there is too much going on with their phones and their infotainment panels and the complex road conditions. You just gotta say it with your whole chest: no-one can reasonably be expected to safely operated a motor vehicle.
