What frustrates me; i have completed my carer in easy to difficult , won every race beginning to end, yet racing against other cars in multiplayer they just fly past me, even on the straits, how is this possible. what need i do to get faster and not be an A1 racer
I think this depends on what assists, if any, you are using. The golden rule generally in the F1 series is that assists will slow you down. The ones that will slow you down most are braking assist in turns and auto-gear in both turns and particularly straights. TC has been another culprit, though in the 2014 game I'm a bit undecided. The built in traction issues could in my view result in faster lap times for TC users, especially if using a hand controller.
Also, setups that work well in time trial seem to me to bear no resemblance performance-wise in multiplayer. I have asked quite a few of those I see doing really fast lap times about their setups and was surprised how many were just using the default.
I use a hand-controller on Xbox 360 and wheel users have a distinct advantage in series of turns when they use brake/throttle overlap, which can be detected from their engine noises. Brake/throttle overlap is next to impossible on a hand controller and difficult enough to master on a wheel-rig.
Another factor is cheats. There are quite a few around. The game definitely does not detect mods on Xbox (can't speak for steam users). I have encountered players who are clearly using mods. One player even admitted to me, proudly I would add, he had modded the game. Check out the top Time Trial times, particularly for wet times, for impossible lap times.
All that said, fast lap times do not always win races. Nobody wins every race, but you will win a good number using your head rather than your "foot", especially into turn one. Smooth driving is another factor. Additionally, I've lost count of the races where I crossed the line 2nd and even 3rd after being knocked off the circuit only to find I had won due to the leader/s incurring penalties. It is easily possible to win a percentage of races even with all assists on - particularly at Monaco and Singapore imho.
Biggest suspect for me though if you are frustrated with straight line speed is the auto-gear assist. If you don't use that assist, a TT steup is the next suspect; next is turn exit - far too complex variable-wise to go into in a short post - but practise and experimentation on approach to turns can be a revelation. There's a sort of "fast-in slow out; slow-in fast out, lift and roll" set of rules.
