Nothing wrong with merging as the lane ends...

Instead of resorting to road rage (which is causing the close calls to be honest), you should maintain speed and allow the drivers to move over.

This is a definite danger. The only solution is road widening. Hopefully that does not happen anytime soon (nightmare).

The curb lane heading up to Shankland should be a right turn lane and the left lane should be going straight through on Euclid Ave. My husband and I have had several encounters with drivers who do not care how they advance on Euclid Ave after passing Shankland. Almost was hit by a motorist who hurried up on the left side of our car so he could turn into the townhouses on the right hand side directly in front of us. I am surprised there have not been more accidents at this intersection.
Afraid of cutoffs

Not a bad idea, but is the road itself, wide enough to deter collisions between those heading north, in this new lane, and those attempting to turn left from Euclid Ave., south-bound, to Shankland?
