Conversion of gas-powered cars to CNG in Thailand

In Thailand, moderately low-cost conversions of gas-powered cars to CNG are accessible. But the cars get a petite amount of miles to a tank that is around 100 miles or so. The drivers also complain of poor acceleration.
Honda offers a natural gas car in the US, for which the demand is very low. This is because the few cars on the roads mean CNG service stations are almost impossible to find. The need of service stations leads to the demand for CNG-powered cars to be low. The restraint of gas prices, in spite of the recent jump back up, means US and European consumers are also feeling less of a pinch when filling up the tank thus reducing the demand for lower fuel cost alternatives.
Even though it is uncertain at the consumer level, but a strong level of support for greater use of CNG power for trucks in the US prevails. It is likely that the government involvement is required, in terms of subsidizing fueling infrastructure or the procurement of CNG-powered vehicles themselves.
