Use of pointless words shows you are aggresive and pathetic which is not appreciated in public communities like this. You don't need to be an adult person or you don't need to be from a nation which has English as its national language. I am not expecting anyone to speak perfect english here, since this is a public community and not always filled with nice and smart people. My point is, do not try to use english in arguments if you don't know english that good.
It is easy to take down both tires of a bike in a short time, and it is pretty hard to drive a bike without undamaged wheels. You will lose control and will get a spin whenever you try to take a left or right, which means you will stop and will get a headshot in matter of seconds.
Since police cars are fast with a good handling, except that lousy ranger, it is probably not so hard to drive them even without any undamaged wheel, at least easy for someone who gives a life GTA:SA-MP.
I never noticed a police car except a ranger. Even if they are spawning random, I am just requesting a little more LSPD, SFPD and LVPD police cars. I hope I made myself clear, thank you.
