For the past five years, I have been ­suggesting that the government provide GPS trackers on all people with dementia who “wander.”

How much time and grief would be saved if you could go straight to where the tracker is pointing?

How much money did it cost to look for just one person in terms of time, ­manpower and various other resources that were used?

How much fear and anxiety would be saved if loved ones could be found ­immediately?

I am sure the cost of such a device would be minor compared to what it is costing us now to hunt for these poor souls.

Not to mention their fright and ­bewilderment.

If people can put small devices on their bikes, etc. and track them down when stolen, is putting one on a human being no less important?

It is true that the size of the Cook Street roundabout is a disadvantage, because it is confusing if two drivers arrive at the same time, with no margin for weaving in.

The strict rule of all roundabouts is that drivers yield to the traffic already in the roundabout.

Many drivers still do not apparently know this.

I always signal a left turn when ­continuing around, which is not legally necessary, hopefully warning oncoming traffic not to drive into me.

Roundabouts were invented in order to keep traffic moving. Some vehicles may have to stop briefly on small ones like Cook Street, but this is far preferable to three- or four-way stops where everyone has to stop every time.

Cook Street is a flat roundabout ­precisely for the purpose of allowing large vehicles to drive over it.

This type of roundabout is common in the U.K. at small intersections.

It does not interfere with the above rule. The main problem at Cook is drivers who approach the intersection as if they were in the Grand Prix and ignore the........
