I'm not sure why it would matter that there's no history of rapid transit on Eglinton. Are we asking so much for people to be aware of their surroundings and not blindly dart into traffic? Do brand new European tram lines have speed limits instituted? And people can jaywalk midblock too, so if you want to be really safe, you'd probably want to lower the speed limit to 25 (or slower) along the entire outdoor portion of the line.
After 5, 10 years of the existence of the Crosstown, will the TTC relent and let the cars run faster? Considering that the Spadina line is pushing 30 and it seems to have only gotten slower as it's aged, I shouldn't hedge my bets on it. There doesn't seem to be any danger of speedy operation on St. Clair anytime soon, either. And that's why I made the comparison to the railway - do the "safety considerations" referred in the post I was quoting stop mattering if the line has existed for a long enough time? Or will it be that as the line ages, there will still be inane safety rules, only this time without the TTC being able to hide behind the novelty of the line?
