Hi Math Teacher, thank you for your answer.

I have not been to Marrakesh in a few months unfortunately, be you seem to actually be there, that is great as you have on site knowledge.

It's a very hard question indeed. I don't know if cars can actually access these small streets or not, maybe they can access some but not others. I'm guessing motorbikes can access anywhere (even if they are not legally allowed to, we know how Morocco is). It's a tough one, but you seem to have more knowledge about the place than me.
