SIR - The front page headlines (T&A, January 28) made me smile. The "six out of ten uninsured cars" subject reported that a survey confirmed what I suspect many of our citizens already believed.

Further to my previous thoughts about the above, and also about the oil wells of the world drying up, it occurs to me that when the latter happens, these criminal acts will be no longer possible.

Since the motor car is dependent on oils in one form or another, unless that mysterious secret formula many may have heard of for years surfaces, fewer cars will be around.

Think of the benefits this could bring. The law would be able to concentrate on other things such as maintaining control of our streets, the wellbeing of the public, etc.

After all, who would steal or hijack a car with no means of movement? So, no MOT fraud, no licence fraud, no insurance dodgers - problem solved!

The possible downside is, because of loss of prosecution revenue from ones previously caught out, plus the legitimate revenue loss from the honest drivers, the Government of the day would probably seek to raise a tax for breathing in the less-polluted air.
