Re a post I did a few weeks ago: having to choose between technology preventing people to drive impaired and surveillance is a false dichotomy. Regulation can prevent that.
However if I really had to choose between tech that can prevent this, and drivers being subject to surveillance I would pick surveillance easily. I have more right to walk safely in a city than you to perform an extremely dangerous, highly regulated activity while maintaining privacy. https://www.cbc.ca/news/canada/british-columbia/police-vehicle-ramming-crash-vancouver-west-end-9.7200915
