Had a sign for utrecht. After 40 minutes only 1 car stopped and it was a taxi asking if i could pay him with favors instead of money. I can only guess what that means cause i said no haha.
But it is a good spot; plenty of cars and plenty of room for them to stop, with a tram stop next to you if things dont work out. Also was lucky with a big cardboard dumpster next to the spot. Have fun
