The Bush administration has suggested it might require vehicle makers to install antilock brakes (ABS) on all vehicles, the Wall Street Journal (WSJ) said, adding that this is the latest safety rule to be reviewed after the spate of accidents related to Firestone tyres two years ago. Industry representatives told the WSJ that requiring antilock brakes alone could cost car makers more than $600 million; in the US at present ABS is standard on many luxury and midprice models but costs consumers $300 to $600 as an option on lesser vehicles.
