Came across this site just now:
http://www.transportdirect.info/TransportDirect/en/
If you drive to work and have been curious as to how long it takes via alternative travel methods, or vice versa, put in your home postcode and work postcode and it'll tell you just how much longer it takes to get public transport... I mean the comparison between driving and public transport It's quite interesting.
For me, the minimum time to get there via Public transport is 1.5 hours according to the site. That's with a bus/walking. Then almost two hours bus/train/walking.
It also says it takes 39 minutes to get there by car, which is pretty accurate. It takes me slightly less tiem than that, about 30 minutes usually.
I'm certainly not getting up two hours earlier
