It is a big problem when cops harangue people, at the very least, for continuing to a safe place when they are lit up, before pulling over. Many times it's an issue of wanting to be where there are witnesses to the interaction in case it goes bad or the cop isn't a real cop. Other times, it's a safety issue where there are plenty of side streets or parking lots immediate to wherever the violation occurred and the motorist simply continues for a block or two and then accesses a spot where it is much safer to both pull over AND for the cop to get out. This gives the lie to the whole safety issue that cops continuously trumpet about how whatever they're doing (usually a violation of your rights) is for both the safety of you and the officer. I can recall at least twice having been pulled over and berated for where I pulled off, AND I didn't continue far at all after being lit up. Not even a block.
