What is the highest possible speed reachable in the game? Using a rail setup with antigrav and boosters, followed by portals at the end of the boosters, seems to be the optimal setup for a speed record. I'm just wondering if anyone's ever gone faster than my setup, which gave 168,000 units per second. https://www.freeriderhd.com/t/1014504-32600-mph - also this track bases a mile on the bike's total distance traveled over 25 seconds which equates to a quarter mile.
