Higher Gas Prices Leads to Fewer Fatalities on the Road
Reason: Higher gasoline prices have caused drivers to hange their behavior. First off, teens and elderly most likely feel the rising price of gas a little more than those of us in our “middle age” because we presumably have higher disposable incomes. Second, people are driving only for “necessities” not pleasure. Vacation travel is down. People are simply doing “stay-cations” where they stay home, or close to home, for vacation.
Third, people are driving slower to save gas. Slower = Better fuel economy. However, this is one I’m not really seeing.
It does seem that folks who own Priuses drive slowly, but the macho men in their raised 4x4s seem to drive even faster nowadays. But I live in the state of freeways and fast crazy drivers, so I may have a distorted perspective. With traffic the way it is, and with most of us forced to drive 15 mph for much of our commute time, it’s really tempting to put our cars and trucks in top gear and drive 85 mph (or more).
Remember, the faster you drive, the worse fuel economy you’re going to get. It’s not linear either, meaning doubling your speed (to keep the math simple and to illustrate this point) will not reduce your mileage by 2 — it will reduce your mileage by 4.
So, if you get 24 mpg at 50 mph, you’ll get 6 mpg at 100 mph. It’s all about friction, both aerodynamic on the outside, and RPMs and load on the inside.
