Recently, a script was added to make it difficult to abuse the enter glitch— the one where you get on/off or in/out of a vehicle over and over to stop someone from hurting you. The problem is, it also impacts people like me who make speedy vehicle changes. I often come skidding to a halt next to an NRG and get right on, but the new system prevents me from doing this because I'm too fast, even though I'm not doing anything wrong. Instead of riding away at a possibly critical moment, I end up having to sit there and wait 2 seconds for it to let me get on. This also happens when I get into planes, as I often jump right out of an old plane right next to the cockpit of a new one to change or roll out of a car right up to the cockpit. I'm sure this would come up in many more situations for many different people given enough time. For example, I could see someone starting to get out of a car, then immediately realizing they made a mistake and someone's about to bear down on them and kill them unless they drive off immediately, but they're prevented from getting in by the system.
Making it so the system only applies if you've gotten in and out of a vehicle with no pauses repeatedly, as opposed to just once, would fix the problem. Alternatively, making it so the system doesn't do anything when the previous and next vehicle IDs are different would partially fix this, and/or making it so the system only applies if you're being shot at.
Without a fix, the issue I'm describing is already more common and annoying, in my experience, than the abuse of the glitch that the system is trying to prevent.
