This board is hung up on speed when that is not the goal in the first place. You will find many systems in Europe as well NA that are not fast as Crosstown or Finch, but are getting riders to/from where they want to go in the first place. Getting people to use transit is the goal and making it easier form them to get them where they want to go to is the goal. Transit will never beat the car, but will help them to have a less stressful travel time, the able to read, listen to music, play games on their phone, chill out and do the media thing.
Doing a trip that is faster than today is what riders want. Again, not everyone is going end to end, but places alone the line. When I do Line 2 from end to end, it is an 45 minute trip and even if it was 50 minutes, that no big deal as it will be far faster than using the bus along doing a number of transfers.
It is a different story doing intercity travel where speed is wanted, but you will find a lot of route in Europe are being built for 200km along with what exist. There are a number that are 300 plus and small in number. In some place, 160 will be the best you will see.
Lets wait and see what will take place for Crosstown in real action than speculate what will take place when it finally see service.
