Industry analyst John McElroy of Autoline Daily said the race is on to get this technology to market.

“I think the first customers who will really pay for this technology are elderly people,” he said. “Especially people who are in their 80s, maybe even in their 90s, who maybe shouldn’t be driving anymore, but do not want to give up their mobility and freedom.”

McElroy said he believes affordable, driverless cars will be in showrooms by 2020.
