The Lost and Damned DLC for GTA 4 is okay. Introduces some new things. One of these things is bike races. I normally opt out of racing, but this feature lets you wield a baseball bat and knock other racers off their bikes. One of my biggest annoyances with races in GTA is that it doesn't let you sabotage the other drivers, so this solves that.
The problem, then, came with one of the races. It takes place on a beach, which the bike obviously does not do well on. But that's okay, I can just hit the other bikers, right? Well, they can hit you too. This would be fine, except for some reason this race borks the physics engine. I get hit and my bike goes flying several meters into the air and off into the water, which is not only an automatic loss of the mission but it also forces me to get a new bike.
So I guess I'm not doing these races anymore.
