Not a helpful shortcut
Funneling drivers onto Dinnick Crescent (Toronto) at rush hour instead of continuing to the light at Mt. Pleasant and Lawrence actually creates a worse, or equally bad lineup, as there is no ability to turn left (west) onto Lawrence. The traffic on Lawrence is solid for several blocks and drivers don't make room for those turning left, which then creates a lineup of cars on Dinnick with angry drivers who want to turn right. It would save time to simply stay on Mt. Pleasant and wait for the light.
