[SOLVED] Car jumping ahead?

[xNick1]

Hi guys,
I'm having some problems with a car.
It doesn't move in a fluent way, it kind of jumps every few frames.
I think it's screen tearing

Could you check it out?
Love file attached.
I tried to print values and stuff.
It seems that my camera is too slow and can't follow the car.

If I set car velocity to 30 or less, it doesn't have that problem.
I face that problem if the car goes faster. (I need it to run fast)

The car has that problem, the player doesn't o.O
