I personally like sharrows and I believe they should be on most roads in the city. Sharrows inform cyclists that they are on a road with shared traffic. There are no exclusions to the rules and no segregation, to get along you have to go with the flow and you have to follow the rules. The chevrons point the way and even seem to demand that you notice them.
But, unlike many of the cycling-related signs on Toronto streets, sharrows are for both cyclists and motorists.
For motorists, sharrows ask that you give room to cyclists, that you must be aware of their presence and tell you to share the space you're driving in.
