I'd disagree on the looking suave bit, it might just be because so many riders are clueless (and this perception being reenforced by selection bias), but someone on an escooter always looks far sillier to me than someone on a dutch style or folding bike, or even someone in lycra.
Regarding lycra - we can disagree on whether you look suave while riding, but a huge advantage of the e-scooter is that you don't need special clothing - don't even need to tuck your pants leg into your sock. You wouldn't turn up to a date clad in lycra - but you can ride an e-scooter to one.
Apologies, I was trying to say that the brompton was the horrifically expensive option.
Upsides is they are a bit better for carrying cargo, can handle slightly rougher terrain, are a little more comfortable at long range and are a little more compact than the more capable escooters.
Both have their place, I was just trying to mention another option that hadn't been included.
