So in GioforPM's particular scenario, he finds transit to be a reasonable alternative.
His location means he drives to the station, rather than walking to a bus stop, waiting in whatever weather, hoping the bus is on schedule and then riding that bus to the nearest CTrain station.
His schedule allows him to arrive early enough to the station to easily find a parking spot.
That station is at the end of the line, so the train isn't always packed and he always gets a seat.
He's a lawyer, so it's very likely that his office is within a block or two of 7th ave and the final leg of his commute is relatively short (not a long walk, or another bus ride from the CTrain station to the stop nearest his office).
As a lawyer, clients typically come to him, so the times he would need his own car during his work day are limited.
I think that any dramatic change to two (if not one) of those points, changes the "reasonable" part of transit as an alternative to driving...
Again, I don't commute, so I don't really have a dog in this fight... I'm just pointing out why I think so many people continue to commute by car. Selfishly, for the times I do have to drive during rush hour, I do wish more people would take transit
I don't know the stats or if it's even true, but isn't the CTrain considered one of the more successful rapid transit systems in North America?
