Today I was going my everyday route to work when I got a front K alert, it went off on a straight road for about 2 miles then it went to 2 alerts then 3 then 4 alerts and the counter kept moving up the scale. yet no LEO in site. Then it showed a rear alert then stopped. Any ideas? I did not see an Infinity or a Bravada near me either...just kinda strage for my daily route to have it go off with up to 4 alerts.
