Cops tougher to locate these days ???

Anyone having a problem locating leo vehicles during winter time ? I ran across 2 leos yesterday and 1 today and my STI was completely silent. They werent sitting on the side of the road but probably pacing / regularly patrolling. since they switch to SUVs in the winter its hard to separate them from regular traffic. anyone have any tips on leo location in the winter ? since they dont run radar or lidar my sti has been useless for the last coupla days.
BTW, it still falses correctly so i know its working.

i live in Florida so its the same cars all year long lol.

Zurk, welcome to the board. Yes, sometimes it is hard to find a LEO yet other times, it's not hard at all. I guess it just depends on the day Zurk.

Where do you live that the PD can switch from cars to SUVs as they please? Here the cops are lucky to get a car that doesn't have 100K miles on it.

NY state. I guess they use the sheriff dept vehicles and local pd vehicles when its snowing (they have chevy SUVs and one gmc 3500 van(!)). i've even seen the van chase one motorist down and ticket him. a one tonne diesel van chasing down a tiny hatchback with flashing lights and everything.
they use small unmarked chevys and the usual marked cruisers for speed enforcement in summer/when its not snowing.
