As Rare as Rocking Horse Droppings

Having now clocked up more than 700 miles in the new Jimny across the country - to date I've only seen one other 2019 new model Jimny being driven.

Makes me wonder just how many new Jimnys are now actually 'on the road' across the UK?

Do Jimny drivers acknowledge each others presence on the road?

Yes and no.
I always wave but so far it's 50/50 if I get a return. As a group it's not quite as acknowledged as my Series Land Rover, most including any Defender variant will wave back. So we need more acknowledgments in any generation in my humble opinion,, so if you want go for it.
I have seen more GEN4 this year (2) than GEN3 (1), so they are out and about on the roads.

I'm trying to push the Jimny wave round here as being rural there's plenty knocking about though mostly gen3. I agree with the 50/50 response but it is increasing. The most confused drivers are the middle aged ladies who look back at you like their brains are actually hurting!

Yep - I'll second the 50/50 experience but I get the impression that during my last 11 months of tenure that has now increased and I now get a return of the wave on most if not all occasions.
I've usually been the one to wave first however; only on three or four occasions have I received an enthusiastic wave first - most notable was two Jimnys coming up through Burford High street one hot day, a girl driving the first, and she was virtually hanging out of the car waving at me, the following Jimny gave me an enthusiastic thumbs up.

Caution if you flash your lights though - I was driving my MG in a built up area and another MG flashed it's lights at me - my return flash of lights and accompaniying wave was interpreted by another motorist whom thought I was allowing him to pull out of a side junction ahead of me which I wasn't expecting :ohmy:

Last summer, on one of my trips (with the RTT on), I met a green Gen3 Jimny with the same setup as me (RTT). There was a very clear and visible excitement in both cars, as we passed each other. Lovely little experience
