I'm thinking if most of our intersections had roundabouts like in Europe, this would be less of an issue. With a roundabout, you need to be paying more attention. T-bone crashes are rare.
Roundabouts are responsible for a lot more accidents.But they are usually just fenders between cars.They are still potentially lethal for bikes.https://www.thestar.com/news/queenspark/2017/08/04/the-roundabout-way-to-control-road-traffic.html I have had 3 close calls this year with cars not yielding when entering.
