"..so what about all the backed up stationary traffic
keeping their engines turning over pumping out toxic exhaust fumes...???"

Well they could TURN THEIR BLOODY ENGINES OFF!! Are they thick or something?

As for "alienating people," tell me of a public protest or demo that DOESN'T alienate. The idea is to make people sit up and take notice. Generally, that in one way or another is going to alienate people. And we have things like the Mail and the Sun, whippers-up-in-chief of confected outrage... I ask you again: is the right way to protest writing polite letters to the Guardian? Or maybe putting up petitions on Change.org that no-one takes any notice of? Or hire-a-celeb (Marcus is rather busy just now...)?? The very idea that non-violent protesters might be thrown in jail for sitting on a road is truly the thin end of a very worrying wedge... we've been forcing people to wear masks...we've been telling families they can't go into their loved ones' homes...we're telling care workers on the minimum wage that they'll lose their jobs unless they submit to vaccination...I wasn't allowed by law to sit with my ill and deaf mother for the last months of her life...we're threatening to turn back innocent people on unsafe dinghies mid-Channel... We should all be bloody worried.
