Not only are the heavy vehicles under scanner but it includes overspeeding cars as well, which have been found 'dangerous'. Talking of accidents, one can't forget the death of Kshama Chopra that went on to become one of the most-talked about accidents in the city. It involved the son of a local millionaire, who rammed his overspeeding BMW car into a Tata Indica car, killing its driver along with Kshama Chopra and her yet-to-be-born child.

In Australia and the UK, there is a device called Intelligent Speed Adaptation or ISA, which is tied into a GPS that is directly linked to the computers that regulate a car engine's functions. This system was being tested to limit the death and injury caused by speeding private cars also.

In Ireland however, it is an offence for anyone to use a speed meter detector in any vehicle under the Road Traffic (Speed Meter Detectors) Regulations, 1991. Under this legislation, it is also an offence to import, fit and supply speed meter detectors and jammers. But the penalty for speeding is a fixed-charge fine with penalty points on driving licence. If anyone is caught speeding, he will receive notice of fine and penalty points of the offence by post.

In most countries drivers are expected to travel at minimum speeds that are safe for the road and according to the weather conditions. In the US, this is often called as the “basic rule”, and in many other countries this rule is known as the “reasonable man” requirement.
