For those asking how to get the easy badge, you have to hit oncoming traffic (other side) head-on (thus the name). You'll probably be in a wreck because, well, road rage usually doesn't end well :)
More money at start (in addition to PsychoMan666's BEST MONEY TIP EVER), crash into the boss 15 times for Mega-Insanity 100k (I pressed and held the up button constantly during the fight)
Minor inconvenience: cannot escape to menu at any time, has to reload page (unless I missed something...)
