Getting rid of the red markers

Instead of coming in contact with those red markers, how about having a /teles command, or /teleports, etc. Its really annoying to be driving around and be stopped because you go over one of those markers. The /teles could lead to the same menu, all that would be changed is how you get to the menu. It would also be helpful in that you could get to the menu anywhere rather than having to get to one of those markers

EDIT: Didn't know there was already a /teleports command, derpherp

We already have a /teleports command

The command is already their.
As for the Checkpoints I'll see about that

Good idea, I agree
