Driving down the freeway this morning, I got a KA alert(3 bars) for 2-3 seconds. Thinking that the cop must be hidding under/over the bridge, I slow down to the PSL.
However, I didn't see any LEO in sight and that was the only KA alert for a brief 2-3 seconds. Weird.
Later tonight, on the same freeway, I encountered another KA alert, this time with just one brap-brap alert. Any ideas what is going on?
