Shrimp is hurrying (see the news page, just slapped up some pics).
About the speed - I've followed Steve's lead and all the vehicles are *much* faster now. At the moment, they can travel 75% faster. As an example (using "Unreal Units per second"), the top speeds of most cars in the past were around 3200, now the fastest cars (Formula One's) are going 5700. It may be a bit too much, will have to see how it works after some testing, and maybe slow it to Steve's 5200 suggestion. There's also an option to revert them to "Classic speed" if you prefer.
The trucks actually do go a lot slower than race cars, and they always have... Dunno how you got a truck to go faster than a Venom
