北京近日实施的黄标车限行政策来得非常突然,虽然此政策在一定程度上可以缓解城区的汽车尾气污染,加速高排放汽车的淘汰,但这种突如其来的措施也招致了广大车主的非议。首先,这种针对小轿车的限行措施有失公平,北京的黄标车共有50万辆,除了30万辆黄标小汽车以外,还包括公共汽车、大客车和载货车,经常屁股冒黑烟、排放高、油耗大的这些大车为什么没有在限行之列?其次,在政策实施之前为什么不多留出一点缓冲时 Although the policy to some extent can ease the automobile exhaust pollution in urban areas and accelerate the phase-out of high-emission vehicles, such sudden measures have also attracted criticisms from the majority of owners. First of all, this limit measure for cars is unfair. There are 500,000 yellow-label cars in Beijing. Apart from 300,000 yellow-label cars, buses, buses and trucks, Why are these carts, which have high levels of smoke, high emissions, and high fuel consumption, not listed in the list of limit lines? Second, why not give more buffer before the policy is implemented?
