More driver's will take loads at a sub standard rate because they will be scared if they don't hurry up and accept it will get stolen by another driver. So some won't even look they will just hit the "Y" button.
If it works as suggested and they do take a "sub standard" load then shame on them. They have the same amount of time to accept or decline as before the change. They can accept or decline based on the same selection criteria they've always used in the same way they always have. None of that changes based on what's been presented so far.
As mentioned elsewhere, dispatch doesn't "make deals" with the first few trucks they offer a load to. They go down the list trying other trucks till someone takes it. This may get some trucks closer to first out a better deal than the old system. Here's how. There are 3 trucks available in Podunk. They need to cover a load. There isn't a lot of time to get to the pickup.
Old way. Offer trk 1. Wait for reply. Declined. Offer trk 2. Wait for reply. Declined. Offer trk 3, with time crunch now taking place, and offer bonus. Accepted. That used 3 time cycles and trk 3 got the bonus since they started at basic pay to trucks 1 and 2. Outcome, 1 and 2 got screwed.
New way. Offer trucks 1, 2 and 3 at base rate. All 3 decline. Offer trucks 1, 2 and 3 with bonus. 1 and 3 accept. 1 gets the run and the bonus since 1 is first out and 3 is third out. With the new system the load is covered in only 2 time cycles, again with a bonus, but this time going to the truck that was first out and should have gotten the right of refusal with bonus and wouldn't have in the old system. Nobody got screwed.
Of course it benefits the carrier as well as far as servicing the customer in less time cycles.
