It's winter... You look at your car outside after it snows six inches. It's now 10 degrees and you've got to get to work. Traffic is going to be horrible. You bundle up, get outside, open your car door, (snow getting all over your seat) grab your scrapper/brush, get snow all over your front while you scrape ice off the windshield, and get into a 10-degree car. Once you start the engine, you debate going inside and waiting for the engine to warm up or just go and look forward to some heat to emerge from the vents so you and the windshield can defrost.
If this sounds familiar, and you don't like the memory, your winter mornings could be much cozier if you invested in a remote starting system. The same is true for summertime and the back of your legs are sizzling!
