Daniel Craig was on hand to unveil the all-new Range Rover Sport at this week’s New York Motor Show.

The James Bond actor headlined the world premiere of the premium 4X4 with the US being the biggest market for the car and New York being the model’s best selling city.

Land Rover is claiming weight saving, lower C02 emissions and improved fuel economy for its new flagship range.

Speaking ahead of the official world premiere at the New York International Auto Show, Land Rover Global Brand Director John Edwards said: "The all-new Range Rover Sport is one of the most road focused vehicles we've ever produced.”

Designed, engineered and built in the UK, the Range Rover Sport will go on sale here in Q3 2013.

First launched in 2005, as the brand's flagship model, the Range Rover Sport's international sales are in excess of  380,000 units.

Less than a third of dealers are responding to enquiries on social networking sites.

Of 40 dealerships approached by the Motors.co.uk team on Twitter, just 12 responded to requests for information on their latest deals and only half of those managed to do so within an hour.

The quickest Twitter account to react to the Motors.co.uk research belonged toRidgeway Group, responding in just two minutes.

Four dealers directed the interested consumer back to their website with no additional information.

Two asked the consumer to phone them and one asked for a follow in order to have a conversation over direct messaging (DM), Twitter’s private instant messaging function.

“Just two of those dealers suggested specific cars which might be of interest to our Twitter consumers and only three tried to engage in a conversation.

“We chose dealers for the study who listed their Twitter profiles on their website and were actively broadcasting tweets, so we were expecting a fairly high response rate.

“What this shows, however, is that just because dealers have a social media presence, it doesn’t mean they are all using it effectively,” Motors used car network managing director Andy Coulthurst.

The police can now test motorists for cannabis at the roadside via new equipment which has been approved by the Home Office. “Drugalysers” - via mouth swabs – search for tetrahydrocannabinol which is a chemical compound in the banned substance. However, follow-up blood tests are required for prosecutions. Drawing blood was previously the only way the authorities could test for cannabis. This, of course, took time as medical professionals were required to perform the procedures. These delays - on occasions - might have allowed the substance to pass through offenders' systems. As such, it is possible that some dangerous drivers escaped their prosecutions. The roadside kit closes this loophole, so the conviction rate could increase as the new equipment is rolled-out. Furthermore, it is likely that the technology will evolve to detect other illegal substances. Those found guilty of drug driving receive similar penalties as drinkers. These include: twelve month bans, criminal records, and £5,000 fines. Car insurance premiums could rise too, and some might find themselves out of work. Most seriously, those who cause “death by dangerous driving” could get fourteen year prison sentences.

Policing and Criminal Justice Minister, Damian Green, said: Those who take drugs and go out on the roads are a menace to pedestrians, other motorists, and themselves. This government has pledged to clamp down on the harm drug drivers cause by giving the police new testing equipment”. Mr Green concluded: “We are determined to ensure the police have access to new technology to ensure drug drivers are caught and punished.”

Cannabis road side drug testing

Cannabis is the most widely used illegal drug in the United Kingdom, according to talktofrank.com. It is popular because it can - on occasions - help users “feel chilled out, relaxed, and happy”. Some people also experience hunger which is called “getting the munchies”. It can also feel as if time is slowing down and some users become talkative and giggly. Whereas that might sound harmless there are more serious effects too. These include: anxiety, suspicion, panic, and paranoia. The substance can also make it hard to learn/concentrate and has been linked to poor exam results. It can also hinder fertility as it cuts sperm count and suppresses ovulation. It can harm unborn babies too. Cannabis has also been linked to schizophrenia, lung disease, lung cancer, and can cause hallucinations. These can be extremely unpleasant. As such, talktofrank.com revealed that research recently published in the British Medical Journal found that “those driving under the influence of cannabis had nearly double the risk of a crash.” Food for thought?
