So my idea is 'thermal vision' ...maybe call it 'visor' or something like that (possibly something less lame haha but anyway).
The idea is that you collect the weapon and initiate it, when active, the user will see speed boost pads that other racers aren't aware of.
Speed boost pads would appear on somewhat randomized racing lines so it would take skill to get the most out of the weapon; they would appear close enough together to ad challenge but far enough apart that you can get the most out of each boost - maybe only a total of 5 boost pads max.
I'm thinking that this can be used as a catch up assist for racers trailing far behind; it wouldn't equip if you were near the lead of the pack.
I think this idea would be really cool because it could be easy to implement and could help with balance and bring slower drivers back into the mix. But it wouldn't be an instant win because you would still need the skill to position yourself over the boost pads and hit the next one.
Maybe, after hitting the pad, it could become visible to other racers behind you for a short period so they will also have a chance to 'ride the wave'. This could ad strategy as another racer might try to follow your line, so hit him with a mine if you have one
