Not sure if you meant weary as in faster cars or weary as in young lads in cars that are a bit 'wreckless'
If you mean faster cars I wouldnt be weary of anything much around the roads. Motorways, yep the Scooby's, some Audi's namely the RS's and S3, TTR's etc but I wouldnt seriously entertain them, I would just wind them up, will give em a less on after a remap though, as long as they aint remapped either lol.
If you mean the wreckless lads, I stay well clear of them.
