I would have to do both legs, as I would also prefer to use public transport than drive in rush hour manchester traffic, the train would even be cheaper!   But even the Manchester infrastructure doesn't supply public transport at the times when I regularly finish working.
I do have empathy with cycling, admittedly, I don't commute, and cycle purely for pleasure.  I dislike the strong anti-car attitude, and the militant "cyclist does no wrong".  I was merely suggesting that there are other ways to go about it.  I had a car inches from my bumper this morning, I didn't pull next to him at the lights and tell him how stupid he was.  I simply moved over, let him go, no more tailgating, no confrontation.  Admittedly, I can and have lost my temper before and confronted drivers.  But, I know immediately, that 90% of the time it's not the right choice.
I take primary when I need to dominate the lane for my safety, such as pinchpoints, narrow 1 way roads, blind country road corners, roundabouts, etc.
If a line of traffic have patiently waited for a short while behind me, for a safe passing point, but cannot pass due to oncoming traffic.  Why not pull over when safe and convenient to return the consideration that they have shown me?
I just don't see everything as black and white, there's a middle ground in all of this.  Not cyclists demanding they have a right to be there, and using those rights because they can.  And not cars forcing their way through because they're bigger and faster.  There needs to be equal consideration.

Have a go, and it will show the issues.  The tests ask more about first aid, and questions about trams, than anything about cycling.  In fact, when I was helping my partner recently pass a test, I don't recall ever seeing a question about cyclists.
It's not entirely anti-cycling, but lack of driver education, that leads to a lot of these issues.
Maybe I'm naive, but I like to have enough faith in humanity, that the majority of people don't want to harm or endanger me when cycling.  But, simply don't realise what they are doing is dangerous.
