30mph/20mph/speed humps petrol car consumption figures
- Steady 30mph (4th gear):
60.7 mpg (small petrol car), 55.6 mpg (medium petrol car)
= 58.15 mpg (average)
- Steady 20mph (3rd gear):
55.5 mpg (small petrol car), 49.1 mpg (medium petrol car)
= 52.3 mpg (average)
- Speed humps (6 over 1/2 mile at 20-30 mph):
33.8 mpg (small petrol car), 27.9 mpg (medium petrol car)
= 30.85 mpg (average)
30mph/20mph/speed humps petrol car consumption differences
- Change 30 mph zone to 20 mph:
increases fuel consumption by 5.85 miles per gallon, or 10.1 per cent.
- Add speed humps to a 30 mph zone:
increases fuel consumption by 27.3 miles per gallon, or 46.9 per cent.
The AA's fuel consumption tests were carried out at Millbrook proving ground by an independent engineer and car tester, using a fuel flow meter.
In 2000, the then Department of Environment, Transport and the Regions argued against reducing the 30 mph limit for fear of increasing emissions.

It's certainly not a new idea or been suggested out of thin air as anyone who researches the cab trade will affirm.
TfL had a significant amount of complaints mainly from suburban drivers about out of sector drivers ranking up.
There was also the issue the issue of the 'hooky bills'.
Then and only then did TfL decided to roll them out to hopefully kill two birds with one stone and we think to let everyone assume that the only cause was the suburban issues and not the trade in forged licences.
That's the chronology folks.
Still you know that, that's why you visit this blog.
