I got my first ticket in the same spot, however haven't gotten one since. Would be nice though (from a lazy perspective ) if it was clear where the trap actually targets but I can also see them other part of the coin. Having a grey area or an uncertain area of where the speed trap triggers improves RP driving in and around those locations.
If the locations were clearly marked or known by everyone then I suspect most people would be speeding as much as they could, which I don't necessarily want or agree with.
Flipping back to the other side, it seems unfair for players (mainly new players) to be given tickets without knowing in the first place that speed cameras exist or where they are. However, some speed cameras (IRL) also have the target area lined and marked for drivers however so that could also be a possibility, but I would like those as a last resort. Whilst they exist in the real world the driving mannerisms on an RP server are vastly different and I think it would have potential to negatively affect the game.
