Can new vehicle technology prevent attacks like the one in Toronto? The experts aren't so sure

The vanattack that killed 10 people in north Torontohas some observers asking if there's a high-tech waytoprevent similar assaults.But experts say technologywon't be enough to stop peoplefrom using vehicles as weapons.

"Technology is not alone the answer to these issues," said JezLittlewood, an assistant professor of international affairs at Carleton University, after a driver plowed through pedestrians on a busy stretch of YongeStreet on Monday.

Alek Minassian, 25, has been charged with 10 counts of first-degree murder and 13 counts of attempted murder. Police have said a 14th count is expected.

Toronto is now among several cities in Europe and North America where vehicles were recently used to kill pedestrians. In 2016 and 2017, driversused that method of violenceinNice, Berlin, Paris, London, New York, Edmonton and other cities.

Littlewoodcompared the number of deadin the 2016 Berlin Christmas market attack, in which 12 people were killed, to themore than 80 victims of the attack in Nice, France.

A report in 2016 suggested that it was theautomated emergency braking system, a European Union requirement for certain vehicles, that may have stopped the driver in the Berlinattack, avoiding further fatalities.

"There's an easy contrast there between the potential implications of these kinds of systems,"Littlewoodsaid, referring to the emergency braking in one case and not the other.

In the United States, the National Highway Traffic Safety Administration (NHTA)has praised a commitment from auto manufacturers to make automatic emergency braking a regular feature in new vehicles. The NHTSA said AEB systems use "sensors to detect an imminent crash, warn the driver and apply the brakes if the driver does not take sufficient action quickly enough."

But implementing technology poses challenges, Littlewood said, and widespread changes in the fleets of trucking and logistics companies taketime.

'There isn't a permanent fix'

Littlewood also describeswhat he callsa "transference" in how people try to inflict mass casualties. When x-rays and metal directors at airports stopped passengers from bringing weapons onto planes, people looked for other ways to do harm, he says.And vehicles have proven a simple and effective weapon for extremists.

"There isn't a permanent fix," Littlewoodsaid.

Ross McKenzie, the managing director of the University of Waterloo Centre for Automotive Research, agrees.

McKenzie saysautomatic braking systems and autonomous driving technologies are enhancements to vehicles, but they don't override human intervention.

"It doesn't replace manual driving," McKenzie said, referring to automatic braking.

"If you turn it off, it's just like a car I'm driving in right now," he said.

David Ticoll, a distinguished scholar at the Munk School of Global Affairs who has studied autonomous vehicles, saysautonomous features are not completely reliable, and must therefore continue to allow for driver intervention.

"I don't think there's a technology solution to this problem at this stage," he said.
