That Crown Vic is a safety hazard - dangerous moving engine parts outside of the hood.
They use Z28's here in CA for revenue operations along 101 and I-5. I was cruising at 80 in lane 3 once and saw this white flash cross from on onramp to my lane about 1/2 mile back, very quickly. I figured it had to be a cop or an idiot, so I slowed without touching my brakes and changed to lane 2. When the cop caught up with me you could tell he was pissed at himself for giving himself away.
No ticket for me that day. Besides, there are no speed limit signs posted on the 8-mile stretch of 101 that I use every day. No signs, no limit IMO.
