I get what you say, and sure laws are different from country to country.
Overall the reasons why you cannot drive bicycles on highways are many, but when you put them all together it mostly fall under one term: safety.
What I wanted to say on my original comment is that trying to put an autonomous driving car in a urban situation is not about checking the speed limit from a road sign, looking at a ground stop or other road signals. If you want a safe autonomous car in an urban center it must be aware of the context much more than “this is a stop sign” or “speed limit is 50km/h”, that’s why I praise Mercedes for trying to solve the solvable problems first and then move to more complex ones.
