Can you rewind replays?

No

Due to a limit on how the replay system works, you can't rewind the replays.

one of the most annoying things about LFS.

That really sucks!
You might wanna check something after the race if the race was good/bad for you.
Is it so hard to add that function to the game?

There are difficulties in making a replay system rewindable, but I do think the problem this causes in league races and post race "debate" means it should be a high priority.

As a programmer myself I can understand how doing the physics backwards is just about impossible, you can only reverse a replay if you take out the physics calculations.

However it is not terribly difficult for them to put in a "keyframe" every 30 or 60 seconds with "all" data that could be used as a starting frame.

This could (I dont really know as it involves knowledge of the LFS engine) require a lot of time to generate ingame, but could be done whilst watching the replay. If it works out so slow it causes a pause we could maybe have a key to press to generate a keyframe and another key to rewind back to it.

In any case making a keyframe system isn't impossible and would be a perfectly adequate solution, where-as a truly backwards running replay might be a bit difficult - depending on how the LFS engine works.

A "keyframe" every lap or every split would be enough I think
