Blast Processing Achievement
Hit 2 opponents with a single Hot Rod Blast
Look for an opportunity when 2 racers are close together and blast away. The best time to use this is in small spaces such as panzer dragoons stage (before you hit the checkpoint there are items just before it, then you go into that small cave and tight drift way). If you have trouble getting this set up two more pads, grab a hot rod and blast them away.
