As 9eighty6 asked, how do you know? Short of standing up and looking back while going over 75 (which does not seem like a good idea), or having a chase vehicle, or a mirror on a big stick, how are you able to tell if it is deploying? I'm pretty tall, but no amount of craning my neck, checking mirrors, etc., has allowed me to see back there? I have no reason to doubt that mine is working (fine when manually deployed) but am curious to see if there's some easy way to tell that I have overlooked.
