As a Wazer, wouldn't be great to be able to send out a distress signal. Tyre change, out of gas, need engine help, etc. Perhaps also car make specific help, in that case a personal setting including car make could be needed.

If another user helps you out he or she would gain some 100 p. To avoid misuse the extra points only should apply when you help a non friend Wazer.

Or turn the other way around and let users state what type of help he or she could provide. No need to get flagged for help if you have no skills with engines. When you're in a hurry the "I can help" must be easily turned off.
