With DOUBLE DOPPLER releasing the british police cars obviously there are nods that fit in with the roles for the cars I would like to see for any fan of the british cars ARV specific call outs, my suggestion is that for say armed driver you could possibly get an option as you do for pit HARD STOP when you pull to the front or the side of the car the car would veer and stop so you could preform youre hardstop with out making contact with the car obviously there would be a chance the car speeds off.

Also the question is about online mode I am unfamiliar with the restrictions that do not allow to use only line will this become a feature in the future?   

Chances are high that a British Callouts pack will come out at some point in the future.

As far as I know, No modifications are supported online, inlcuding LSPDFR, if you manage to make a RPH bypass, you could be banned.

Thanks for the reply I might of been a bit vague, what I mean is link FINKONES radio were you get an option to do a pit you get the same option to do a HARDSTOP, this is my mind would allow for a pursuit of the car and then at your choice you can perform the manoeuvre, obviously in britian 2 ARVS or more would do it but with AI smashing it to everything it sort of spoils the effect sometimes.

Also in regards to my question I meant will LSPDFR support multiplayer in the future or will rockstar attempt to block this I only ask because I never played gta4 LCPDFR so I am unsure of the mechanics that allow LSPDFR and if GTA4 had the same issue when it started.
