Each year, thousands of car accidents occur in the US, which lead to death or severe disability in many cases. Approximately, 33,000 lives are lost every year, so it is certainly a big concern. There would be a relief, if a machine can help reduce this figure to 3,300. If only one death occurs with help of a machine, instead of loss of 10 lives due to human mistakes, wouldn't it be a better way?

Author Malcolm Gladwell talked to the venture capitalist Bill Gurley on 'catastrophically imperfect' network of cars. Gurley also talked about the biggest negative side of self-driving cars. They talked about the matter in a keynote address at the SXSW Interactive Festival on Sunday.

According to Gurley, who invested in Uber and other disruptive technologies, humans will not easily accept the deaths caused by a machine, whereas human errors are still tolerable. According to him, "I would argue that for a machine to be out there that weighs three tons that's moving around at that speed, it would need to have at least four nines because the errors would be catastrophic".

There is no doubt that driverless cars would be made in such a way that they work properly, i. e. near perfect. But there are many problems associated with driverless cars. Many circumstances make it difficult to use the technology.

It is a challenge how a driverless car can be programmed in order to give way to an ambulance. It's also needed that such a car responds to an officer directing traffic. Many other concerns are related to weather, flooded streets, heavy snow and many other conditions.

Ryan Eustice, who is developing algorithms for the maps, which are intended to be used by driverless cars, came in support of the these cars.
