I'll start by saying I didn't watch the video. But to me this is somewhat true. Vehicles designed to go fast are just boring as heck to drive at legal limits. My 650R wasn't fast but I always had to keep the throttle in check because I could easily end up going over 100 in the city if I didn't pay attention. Had a WRX and that thing never felt right unless you were on the highway. It just wanted to go faster all the time. But yes, you can obviously still drive it slow. Lower powered engines need a bit of effort to go fast and don't feel like they're eager to go faster all the time.
To each his own I guess. I have a 2010 STi hatch and don't get that feeling ("never felt right unless you were on the highway") at all. It's quite comfortable being short-shifted and tooling along at the limit in town. As you say, ""you can obviously still drive it slow." Indeed.
Just this weekend I was out extensively on the Tuono, both city and country riding. This 175HP "supernaked" is a total and complete pussycat and very content at legal city speeds.
I don't get the sensation the STi feels "eager" to go faster and faster all the time or that the bike is "eager" to run at higher power all the time though I acknowledge both have the capability to do so when called upon. At steady, in-city speeds their "eagerness" feels little different than any other car or my Fazer (for example.) Sure, the STi rides more stiffly than a tipsy, wobbly Camry and can effortlessly accelerate harder than a sickly little Corolla but that speaks to capabilities, not some sort of "eagerness" on the part of the inanimate object.
I think some of the issue is that some folks find driving
anything at legal limits "boring." Driving a Camry or CBR300R or a CBR600RR is going to be "boring" at 50kph or 100kph on the roads and byways we have available to us. Maybe it's that "fun" on a firebreather is so much more accessible and easier to find
if you want it. The same applies to cars: Corvettes and GT-Rs are perfectly capable of being driven at the same pedestrian, boring speeds as the champagne-coloured Corollas we see everywhere yet, when asked to, they are able to deliver a much more enlivening experience in any situation.
I think it's a psychological thing: SSs and supernakeds, for example, have so much in the way of capabilities that maybe some feel they're shortchanging themselves (and the machine) if we don't use them all the time in that way. Some succumb to this logic and use more of the capabilities when perhaps they shouldn't. That's not on the machine, that's on the rider/driver; it speaks to maturity, wisdom, experience, personal responsibility, intelligence etc.
