I do wonder sometimes whether certain researchers are quite plugged into the same universe as the rest of us. Today’s example comes from the British Medical Journal where some researchers have claimed that raising the speed limit from 70 mph to 80 mph on the motorways (something that is under discussion politically) would lead to an increase in obesity.

“Health concerns outweigh any economic benefits of raising the speed limit on motorways, according to an online report in the British Medical Journal.

Increasing the limit from 70mph to 80mph is being considered by the government.

The authors say a higher limit could increase gas emissions and air pollution and could lead to increased obesity, with more people taking advantage of shorter car journeys.

That tagging of obesity onto the end there seems really to be just appealing to the fashionable health scare of the day. These things do seem to rather go in waves.

However, as a friend has calculated, it’s not really very likely that a higher motorway speed is going to persuade many, if any, off their feet and into cars for a journey.

“…assuming the driver takes 1 minute from leaving home to joining the motorway at an average speed of 20mph, and 1 minute from leaving the motorway to arriving at destination at the same 20mph average, what is the minimum distance from start to finish for which she would save 1 minute of travel time by travelling at 80mph rather than 70mph on the motorway, assuming instant acceleration from 20 to 80?

Answer: at 70mph she travels 1.16 miles per minute, at 80mph 1.33 miles per minute, so X/1.16 = 1 + X/1.33, solve for X and you get X(1.33 – 1.16) = 1.16*1.33: X = 1.54/0.17 = 9 miles (plus 2/3 of a mile either side)

I’m glad that the authors of this paper are devoting so much effort to safeguarding those among us who would rather drive 10 miles than walk it because it’s one minute quicker than previously.

It’s really just not one of those things that any of us in this universe would think to add as a warning, is it? Obesity as a result of higher speed limits?

They need to raise the speed limit to 90mph on I-15 going thru Vegas. Last night I was driving an Aston Martin V12 Vantage through there and the fucking thing wouldnt go any slower.
