Hey, thanks, I appreciate the feedback.
I personally like the traffic in street racing, but I can see why you might want to focus on driving the route. Perhaps I'll add a "no-traffic" option.
The gold times are all beatable (although I struggle a bit with "East" and "Flats"). For the tighter corners you actually maintain speed better if you slow down just enough so that you don't drift.
It occurred to me while recording this that the waypoints around the "East Suburbs" area might be a bit misleading. I.e. you can go straight, then make two 90 degree left-turns, whereas the arrow suggests you should turn left straight away, which then forces you to make an extra hairpin turn. Perhaps I can tidy that up a bit.
I haven't seen (noticed?) the hard turn issue yet. Which version are you playing on (browser/download/pico-8 etc)?
