I suppose that depends on how resource intensive it is and how long it takes.

If you have to go to the teleporter building and wait in a long line, it'll be more like "oops I left at home."

If teleportation is basically free and you carry the device on you, it'll be only slightly worse than walking.

The real bad time is if teleporting is portable and easy to do, but expensive. Then we'll really get ourselves in trouble.
