If you are, for example, half way through lap 14 and you pull over and teleport back to pits your controls get locked for 60s (much longer than tire change and refuling times) and when you come out of the pits you are restarting lap 14. In 99% of situations teleporting will lose you more time than doing a normal pitstop. The 1% where it can be considered cheating is if your car gets so badly damaged just before the start/finish line that the repairs will take longer than 60s, then you could just crawl over the start/finish line to move the lap counter forward and teleport, saving you time... Of course the chance of this happening perfectly is so small that it's not even worth worrying about.
