In general, he declared, people have always been willing to commute for about a half-hour, one way, from their homes each day.

This principle has profound implications for urban life. The value of land is governed by its accessibility—which is to say, by the reasonable speed of transport to reach it.

I have been moving this Alpha Omega Elite car seat between Hyundai's, Chevrolet's, Nissan's, Honda's and Toyota's over the past few months. All I have to say is I feel for parents everywhere moving child seats from car to car.

I do not know if it is design or they are simply a PIA but this is a PIA.

Sorry parents everywhere and I feel your pain.

An enormous transformer was carried from Didcot power station, but was transported at just 4mph as it weighs an earth-shattering 640 TONNES.

The huge vehicle is 100m (328') long and 5m (16.5') wide and took up two lanes of the motorway while it crawled to its final destination at walking pace.

It began its slow journey in Oxfordshire on Friday, causing 13-mile long tailbacks when it wound its way along the M4 on Saturday....

I am urging the Illinois legislature to vote no on SB 2356, which would increase the speed limit to 70 mph from 65 mph on Illinois' roadways. The bill has already passed through the Illinois Senate and awaits a full vote by the Illinois House.

There is an enormous speeding problem in Illinois already and this will only exacerbate the problem.

According to AAA Chicago, speeding is responsible for more than half of Illinois' 900 plus roadway fatalities, and more speed will not help lower that statistic.

Between 2008 and 2011, Illinois' roadway fatalities dropped 12...
