Let me clarify the headline first: I defeated a laser trap set by a Florida Highway Patrol officer! I was travelling 90-100 driving a rented 2020 BMW X3, in the left-most lane while blowing by a slower vehicle, when the alert tone sounded. I guess the start up sequence has me subconsciously trained to the alert signals, so I urgently but smoothly hauled my speed down to 80, then did 77 as I cruised by the patrol car hidden behind the median guardrails. I reacted before the first tone was even finished sounding and by the time the DFR8 announced "laser" I had already reduced the speed as described. I had never heard a laser alert tone before in practice, just the start-up tones. I watched a TED talk that suggested my reaction time was probably somewhere between 5-20 milliseconds for the laser to either return some type or error or the reduced speed. The pulses are 5 milliseconds apart and it the laser guns need two returns to measure speed. I'm amazed I was so lucky to react that quickly. I mainly relate this story not to brag but to share my experience which I thought was impossible; lasers can be defeated if you're fast enough on the brakes, so one should definitely try if they get hit with an alert. Obviously conventional radars are no problem at all for even this lower-range Uniden; the scatter gets picked up long before you will see the cop. As for my rating on the suction power, it is ok once it on there. The issue I have is when I remove it for security; the cups can get cold in the glovebox and stiffen up too much to function. I usually have to warm them in my hands for a while to get them back on.
