My blood pressure is down...literally (came back from a physical). I used to drive very aggressively (in Houston traffic it's survival of the fittest); I used to get so worked up on people cutting me off and sneaking themselves in front of the merge lane etc.
Now, my attention/concentration on the MPG gauge prevents me from concentrating on other people's stupidity! I feel more relaxed as I am able to better tolerate the traffic conditions. Save money on gas AND add years to my life - priceless.
I couldn't agree more! Same impact on my life. Don't know how long you've been driving, but I've been at it (aggressive driving) for nearly 30 years. This car changed me overnight!
