There's the (controversial) concept of "Risk Compensation", which covers some of the same ground; when we feel safer driving (eg, when we start wearing a seatbelt), we unconsciously compensate by driving with slightly less care. There are two problems with this: the risk is often transferred to other people, and the magnitude of the compensation is not guaranteed to be the same. The Netherlands is a great example of reworking the streets to make them better (see for example: https://www.theguardian.com/cities/2015/may/05/amsterdam-bicycle-capital-world-transport-cycling-kindermoord https://www.theguardian.com/cities/2015/may/05/amsterdam-bic... and https://bicycledutch.wordpress.com/2011/10/20/how-the-dutch-got-their-cycling-infrastructure/ https://bicycledutch.wordpress.com/2011/10/20/how-the-dutch-...). There was a large and well-organised campaign starting in the 1970s.
