I don't know if this is possible but one of the fun things we used to do when knocking about in boats is drive in figure 8s to hit our own wake. I tried that in The Crew 2 and it seems like our wake dissipates very quickly. Might just be a limitation of what the physics engine could handle but I'd love to see wake persist a while so we can jump over our own wake and stuff.
Sadly this is one of the things they bragged about too in one of the game events. They mentioned how you need to be aware of wakes from other boats or something but really it doesn't make a difference. Sucks to have poor water physics. It would be great to have some real waves to jump.
