I haven't yet seen any set up like that. The ones I've seen (mostly in
Virginia) so far have the traffic "queue-up" light placed well before the
acceleration lane so one can still hit the acceleration lane at a pretty good
clip without a lot of effort.

If the engineers have set up some as you describe, they had better go back to
traffic engineering school (in my opinion).
