Big +1 to this, I've found quite funny when I have to drive across the entire GTA:SA map to deliver a securicar full of cash (imagine that it had 4 briefcases inside) and they payout is only $3,000 or so. What it looks to me is that this payout is a slap in the face of the robber that had driven a 57km/h Securicar over 4 minutes with 5 or 6 stars on their WantedLevelPoints.
