I don't own a Tesla (yet)
I don't own a Tesla (yet) because we live in a rural area with absolutely no recharging facilities available and for us, a battery powered vehicle just isn't a practical option.
Boyh my wife and I have both been Jeep owners for years and we're quite familiar with the "Jeep Thing". We drive a lot of miles in the Jeeps and my current Commander (my second one) has logged 350,000 miles and is still going strong.
The Commanders are the best multipurpose vehicles I've owned, and in the past 60 years I've owned a good many different vehicles. They can carry 7 people, pull trailers up to 7,500 pounds, offer adequate comfort for large guy and are versitile on long trips and well as off road.
As for the Jeep community, I find it's not what it once was. A great many soccer moms and first time Jeep owners have no clue. For them, a Jeep is just another car and they don't understand why you wave as you pass on the road.
Your article didn't mention the one vehicle with the strongest world wide owner community -Harley-Davidson. I've been riding Harleys for almost 60 years and no other product, motor vehicle or otherwise, has a loyal following like Harley-Davidson.
The "Harley Wave" has evolved into a nearly universal salute within the biker community, even among folks riding other brands.
And a final comment about product loyalty and communal association. Look at the people who have Harley tattoos. No other product is so revered by it's owners that they permanently display the brand on their bodies.
