Needing a ride-how to get a driver's attention

Have you guys ever had the problem of needing a ride in a transport vehicle (especially on Arad) so that you do not have to walk long a distance. Or, have you been the driver and not realized that there were people who needed a ride?





I thought an interesting idea would be to have a "call out" command on the command wheel where you whistle or yell out "I need a ride" (or something to that effect) to get the driver's attention so that he can stop for you and other comrades.





What do you guys think? Discuss!
