I have heard somewhere that according to the devs it takes about 40 minutes to get from coast to coast in The Crew 2. That number seemed a little high to me, so in the closed beta I gave it a try myself. 😛
Here you can see me driving from the player house in New York to Santa Monica Pier in Los Angeles with the Koenigsegg Agera hypercar. The car is stock and I am not using any nitrous.
Note that starting from New York is probably not the fastest way to get from coast to coast. I just wanted to pick some iconic start and finish locations.
Unfortunately the GPS in this game gets messed up in certain parts of the map (and then won’t fix itself until you crash), for example when taking the exit here at 3:38, so for this trip I actually had to memorize some of the turns before the run. Hopefully this issue will be fixed by the devs at some point.
