COMING UP:Share Opener Variant 4



>> The Canadian providence of Ontario is trying to build itself as a quote Silicon North. And like a tech company, it's trying to sell its cold weather as a feature rather than a bug. While much of the testing for self driving cars happens in places like Arizona or California where the weather is warm, developers have to be able to prove their autonomous vehicles can brave real world elements.
And that's where Canada comes in, says Reuters correspondent Allison Lampert.>> Renesas Japan has set up its autonomous vehicle testing site here in Canada where snow, ice, and sleet can reek havoc on car sensors. Researchers are looking at using things like coatings on camera lenses to protect against snow and ice.
>> Self-driving cars use a system called Lidar similar to radar, but also rely heavily on cameras and sensors. If you've ever driven in snow and sleet, you know you can't count on that rear view camera which gets covered in grime. And it's hard to see road markings in snow says John Bostick from Renesas.
>> And so we've already set up the technology here such that, if we couldn't see the lane markings, we could still drive this course successfully. Just by seeing the landmarks on the course and with our high definition map.>> Weather is just one more challenge facing developers. The industry saw its first fatality after a self-driving Uber SUV struck and killed a homeless woman in Arizona Sunday night.
Ontario says it's closely following the Arizona investigation, and would take action if warranted.
