Nah that would be unhinged, i usually go in the part of the city where theres a completely seperate bike and pedastrian path. Theres also a part near my house(up on a hill) where i can(more like could, in not such a daredevil) overtake cars. Of course this is a pretty serious downhill but the same way you do it, after you already accelerate its easier to keep the speed tho im a pretty big guy so the wind resistance is insane. But its a pretty good feeling when i get to the city faster than the bus by like 10-20 minutes tho once again i live on a hill so getting home is torture. I also went to an event in the city with friends once and i had a bike cause thats the way i got there and we started at the same time, them with a bus, me with bike and it was so funny when i told them i was waiting for five minutes.
