Bumps On the Roof Of Our Cars?

Nissan with bumps on roof.

If you drive on roads like the A13 you’ll find quite a few drivers are sticking to 50 mph and cruise control to save fuel.

Here’s another idea (no guarantees that it works!)

We found a new article on the Pacific Standard website that’s quiet intriguing.

It’s about a Californian deep-sea diver and inventor who’s looked at the tiny bumps on whales. He reckons that if you put the same type of bumps on car roofs you improve the aerodynamics and save on fuel:

The pods—spaced four inches apart and located 10 inches from the lip of the roof—reduced aerodynamic drag by 5 percent when a two-door VW Golf was driven at 65 miles per hour….

The pods come in loud flashy colors. Some can be permanently glued to the roof. A more expensive model attaches via magnets. Prices currently range from $60 to $100, but those, Evans said, will come down to reflect how much a driver might save in a couple of months.
Aside from the monetary relief, Evans said the pods offer drivers the opportunity do something about climate change.
“People don’t want to be told what to do; they want to do it themselves.”

The sellers of these bumps have a website here.

Does anybody fancy being a pioneer? Should County Highways invest in a set and see if they work?
