Forgive me if I sound arrogant, but blacklist 6 isnt really that tough.... Yes, I agree, teh spikes can be nasty, but there wont be that many spikes if you stay in closed spaces, with not uch space to move arond...
I never got busted untill i reached the bounty of blacklist no. 2..
I then had to buy the carrera GT.... my lamborghini didnt get me any further... but after carrera, i got the BMW from razor, so i gave the carrera up...
From what i learnt of MW,
in low heat levels. keep to the freeway/mainroad/whatever-its-called...
in high heat levels, keep away from the city, but try and find congested spaces...
when there are a lotta cops behind you, hit a speed breaker adn take a u turn... i dont know if it makes sense, but there is less chance of meeting a cop in heat levels 4+ when you do this (from experience)
Try and keep out of sight of the cops... (take turns, etc)
and, of course, stay away from tradffic..
The copters can be really irritationg sometimes...
as for roadblocks, KEEP AN EYE ON THE MINIMAP... especially when you hear radio activity...
i too found rhinos hard to spot, so i dont really have any tips on that...
