The infrastructure in Toronto is just awful. I will never drive downtown and have no intention of ever doing so. Too much congestion, construction, road closures, pedestrians, bicyclists, expensive city parking etc. Not worth it.
The Gardiner Expressway is awful. The 401 is always a mess, no matter what part of the day. Driving in this city sucks. Too many roads now have a 50 KM/H limit and some major roads don't even have proper separate left-hand or right-hand turning lanes. Bike lanes are popping up everywhere, taking away a lane of traffic. Buses clog up the roads as well.
Even the traffic out in the suburbs is pretty awful during rush hour and the weekends. Mississauga has too many stoplights on busy streets like Dixie and Dundas Street, which are always a mess.
This city needs another subway line running east/west, but that will never happen and it's way too expensive now. As well, they need more commuter rail trains that go into the downtown core.
Toronto is pretty backwards for what is considered a world-class city.
