Machu Picchu, the remains of a 15th Century Inca city, is Peru's most popular tourist destination, and a Unesco world heritage site. Yet a continuing dispute over the buses that take visitors up to the mountain-top site recently saw some 1,400 stranded tourists needing to be evacuated. Cristian Alberto Caballero Chacón is head of operations for bus company Consettur, which for the past 30 years has transported some 4,500 people every day to Machu Picchu from the local town of Aguas Calientes. It is a 20-minute journey, and the only alternative is an arduous, steep, two-hour walk. He admits that in the past few months there have been some conflicts between people from different communities here.

The federal government estimates that V2V connectivity could ultimately prevent or reduce the severity of about 80 percent of collisions that don't involve a driver impaired by drugs or alcohol.

A Tesla electric car crashed into a tourist bus on a motorway in northern Germany with the driver claiming he had activated the car's autopilot system. The driver of the Tesla car was injured, while the 29 people on board the Danish bus were unhurt in the incident on Wednesday, police in Ratzeburg in Schleswig-Holstein state said. The 50-year-old driver's car hit the bus as it changed lanes outside the northern town of Gudow. Available for Tesla's Model S electric cars since October 2015, the driverless autopilot system has come under global scrutiny following fatal crashes in northern China in January and in the US state of Florida in May (file photo) 'We will now have to look into why the autopilot didn't work to prevent the crash,' police said in a statement.
