Elon Musk's lidar bashing has grabbed public attention and dominated conversations about autonomous drive technology, but his dismissal of high definition mapping has flown under the radar. According to Shaun Stewart, a Waymo veteran and new advisor and investor at the mapping startup Carmera, we're missing out on an important discussion. Stewart talks about the importance of mapping at Waymo, why Carmera's approach was so appealing to him, and how he's supporting their effort to build out HD maps that faithfully reflect the changing environments that autonomous vehicles will have to navigate.
