There may be a rare case or two out there, but we'd bet that the average
owner would never want to be seen on a scooter, nor would a Vespa rider want to be seen driving a Hummer. The kind of person who chooses to commute on a scooter probably is morally against what the Hummer represents, and those who choose to drive a Hummer to work probably don't care that the scooter is a more efficient means of transportation, right? Sure, Hummers aren't really any worse than any other SUV out there with an equally sized-engine... but few would argue that they are certainly perceived as different.
With all of that in mind, it's not surprising that when the two camps get together, sparks fly. If you're interested,
for the original post which stirred the ire of the Hummer drivers, and then
for the response.
