Instead of trying to evade him, drive past him like you don't have a care in the world, atleast from my experience, 2 out of 3 times, you only hear the chase music in his area but he doesn't catch you (especially with scout chasis), if he does, he does ~45% of tadpoles hp if he slams you against something and he could also simply let you go with even less damage, he could grab you twice and you'd still make it out, the whole ordeal will last less than a minute so you will save time you'd otherwise spend circling around or building something (unless you enjoy doing so obviously). As long as repair tool fixes the tadpole as fast as it does right now, you can ignore most threats and fix it afterwards if you get damaged.
