OK, I have an example of an "impractical" vehicle I do own.
Always liked bikes. Back when "American Chopper" was a popular show, I got the itch, and decided to build a radical chopper myself, from scratch, so I did.
Bike is beautiful to look at, but... With a 12 inch over front end, and lots of rake, it is a difficult bike to ride at slow speeds. You have to be up on it. With no rear suspension, it rides harsh. The only give is if you lower the air pressure in the rear tire a little. Cause it sits so low, you leave a spark trail at anything resembling leaned over in a turn.
Stylish as they are, there is a reason the chopper fad ran its course, people just needed to be reminded of what was learned in the 1960's.
Mine still sits in the garage, with maybe 200 miles a year put on it. It is a blast WOT on a smooth straight road.
