Richard, that could be the best one yet!

Good point D, forgot about that – traffic cannot possibly be a collective noun for cars because it leaves out cyclists (and pedestrians, for that matter). Reminds me of the Critical Mass slogan – “we’re not holding up traffic, we ARE traffic”.

to include the notion of spewing … perhaps a Vomit of cars? Or a Purge of cars, which would capture the notion of destruction as well as spewing?
Good luck with that snow!

I usually say I would take snow, rain, hills etc. over traffic. However traffic that is at a stand still is easy to by pass.
We haven’t had too much snow here this year, but when we have received snow it has been near impossible to ride…Sad thing is we’re expected to be getting up to 30cm tomorrow. City couldn’t clear 4cm, not sure how they handle 30.
If a city actually clears the snow properly from the roads AND bike lanes, riding in the snow is one of my favourite things to do.

Just as I was about to hit submit, our pro-car morning radio guy was talking about a study in the States on how much money people waste sitting in traffic…Keep in mind, GTA highway traffic costs ALL of Canada $5billion each year.
When thinking of a noun for traffic/cars, we should somehow include the wasted money and pollution they spew out.

More appropriate to cars than crows, for sure, Maggie.
