Dr Judit Nadal, a pioneering researcher into proteins, died instantly when her tiny electric car struck a Skoda Octavia in Hendon, north-west London, last Monday. Photos show that the car was torn neatly in half. Dr Nadal was thrown clear of the car.

An ambulance rushed her to the Royal London Hospital, but she died at 8.21pm.

Concerns have been raised about the safety of the Indian-built eco-car in recent years, with Top Gear magazine being a vocal critic after a crash test at a mere 40mph demonstrated that it would inflict ‘life-threatening injuries’ on its occupants.

The fact that the G-Wiz is not technically a car, but rather a quadricycle, means that it is not legally subject to the same stringent road safety tests as full-sized passenger vehicles. Its UK distributor, GoinGreen, say that they voluntarily perform their own tests on the car. This may be true, but the manner in which the little urban runabout snapped in half in Dr Nadal’s crash is undoubtedly a cause for alarm. Greater risk of death in a crash

In 2007, the Transport Research Laboratory decided not to use their most expensive crash test dummies, worth around 130,000 each, when testing the G-Wiz because they were concerned that its flimsy build would result in the dummies being annihilated.

Now government officials are calling for the cars to be banned, along with AA president Edmund King: “The G-Wiz is classified as quadricycle hence exempt from standard testing. It should be banned as it is unsafe.”

Costing under 10,000, the cars have become popular in the capital in recent years thanks to their compact size and exemption from the 8 congestion charge in central London. Their batteries can be topped up from a standard household socket, and above all, they are environmentally friendly, something that is becoming increasingly important in these eco-conscious times.

While environmental awareness is obviously important, it arguably shouldn’t take precedence over saving lives. Gordon Murray, the South African deisgn genius who first came to the world’s attention as the man that brought us championship-winning F1 cars in the 1980s, thinks that the UK should take a leaf from Japan’s book when it comes to city cars.

He told businessgreen.com, “To date, the only government that’s taken urban cars seriously is Japan,” he said. “It has had the Kei car format for decades, which makes up [a substantial part] of the market in Japan.”

The EuroNCAP safety scheme, he argues, has been very successful but has resulted in cars that are dangerous in an urban environment. “For urban cars, we need a crumple zone that starts working at 15 to 20mph, not at 40mph.”

In September, Murray revealed the designs for his iStream T25, which is shorter than a Smart ForTwo, and yet can comfortably seat three people and is designed to pass full-size car crash safety regulations.

As we become more eco-aware, let’s make sure we don’t compromise on safety as well. Compact cars shouldn’t equal huge crashes.
