LEWIS HAMILTON will know when the time is right to quit Formula One – and when he does he will stop racing for good. Coulthard, who will be on Channel 4’s coverage at the season opener in Bahrain on March 27th and 28th, said: “If he truly believed it was time [to quit now], he would not have been in Bahrain for pre-season testing. “But when he does decide that’s it, I don’t believe he will drive one more lap in a racing car. “In my case, I got the realisation at the beginning of 2008 pre-season test. I knew it was time for him to stop having asked me the question. “It is like any relationship, you just knew in your heart that it is the right time. “But we have to remember as well, this is not his first pre-season rodeo.
