In answer to 'Two-wheel winner' from Dave Gardner (Talking Point, 7 April) his scooter may be able to achieve low running costs of 100mpg-plus and the ability to sail past traffic queues, but this type of transport is not particularly safe on today's congested roads.
And scooters are certainly not a green option as the two-stroke engines are dirty, smelly, fill the air with part burned oil/oil mist and soot, and are extremely noisy.

While I agree in general with Dave Gardner describing two wheels as a commonsense alternative to public transport for short commutes, I disagree with his particular choice.
The two-stroke engines that power scooters are environmentally unfriendly and inferior compared with the four-stroke engines generally used on motorcycles.
May I suggest the bicycle as an even better short-journey alternative.
