Save some money...drive the speed limit...
Yay Fred!
You can wait until you are my age and decide that it's pointless to be in such a hurry to shave a few seconds or minutes off your commute, or you can listen to Fred and learn it earlier.
And a note concerning your auto insurance. Some insurance companies will refuse to renew your insurance without explanation if they learn that you own a radar or laser detector. Geico for certain, and there are others.
How do they learn that? They ask. When your insurance is up for renewal in a couple months they'll give you a friendly call. They'll ask you if you own a Citizens Band radio. You'll answer, and they don't care what your answer is. That question is simply to prime you to answer the next question - the one that counts. "Do you own a radar detector?" Answer yes and your business relationship with that insurance company is over.
