Here’s my London GP around Buckingham Palace: http://www.gmap-pedometer.com/?r=4486051 I had to put in that little fiddly bit just to slow the speed into the next corner a little bit. I think it would be pretty cool and a great, unique shape.
I know Toronto has a street track already, but I thought I’d try a new one: http://www.gmap-pedometer.com/?r=4486071 Obviously the grid system doesn’t lend itself to great tracks, but there’s enough variety here, plus it would be interesting to mix the challenge of a street track with the necessity of having to use low downforce set-ups, particularly with the half-roundabout towards the end of the lap.
I have no idea where the pits would be in any of these, though!
