As much as the target following behavior makes bots engage more quickly and keep attacking, the ramming behavior does somewhat ruin it as the winner will usually be the bot that ends up on the bottom (or has lasers). At least with random walk behavior, you tended to get multiple encounters between multiple bots with relatively few collisions, even if it took a lang time to get a complete kill.
I'm planning to add a system to keep an optimal distance to the target, based on what the broadside had, but I can see the situation getting messy for bots designed to go forward only, especially in tighter parts of the arena. I'm thinking that adding a second set of rear-facing hooks to do collision avoidance might let the bot get away from its enemy more easily. Kinda makes me wish I'd kept the whole reversible drive and navigation system.
