I think a Supply/Demand system for truckers is a good idea for the server, for incentive for people to do the job more. There's a problem with gas stations having no fuel, gun stores having no guns and dealerships having no cars. I think if the jobs were worth more(especially fuel) depending on the need for it then people would do it more. As it stands I know I dread doing the trucker job as it often times has you going from Los Santos to Blaine County or Paleto Bay to drop fuel off and only getting $600-$900 for it and then driving back to Los Santos. In the same amount of time I could have just driven a bus around Los Santos for 5 minutes, did one route of 15 stops and made almost $1300 and then do it all over again.
