The idea is pretty simple - a link is established with the first car in front of you (within x range) and forces them to engage their brakes, causing you to pass with ease.
Maybe the duration could last so it'd be good for more than one pass.
For balance's sake give it a slight windup time so that if you are trying to pass someone with an active Overtaker you may be able to escape its range before a proper link can be established.
I played tons of Rollcage Stage 2 way back in the day, then when we got a PS2 Jak-X Combat Racing struck a similar chord. After that it was Wipeout Pure and Wipeout Pulse on the PSP. They all had some pretty interesting weapons, might be a source for inspiration.
