It's two things:
On the one hand, WRX Douchebags. I have some upcoming video content about that, and how Subaru embraces it (there's a marked difference between how I've been treated as an Outback owner, Ascent owner, BRZ owner and now WRX owner at dealers).
On the other, it's because the car is a bit fucking bonkers.
Every car has a groove where it wants to sit. Lowest NVH, most physically comfortable.
With the BRZ as I had it reconfigured, that groove was like 65-70mph in 6th gear. That is, a lot of the time it discouraged you from even going the speed limit.
The WRX... The groove is 50mph in 3rd. Unlimited above that. It also accelerates FAST once it hits boost compared to a normal car and there is no perceptible NVH difference between the speed limit and 100mph.
So if I apply the same mental rules as I used to drive the BRZ (and prettymuch every other vehicle I own) it gets you into heinously illegal situations fast.
Take a freeway onramp. Once you hit the ramp, foot all the way to the floor. By the end of the ramp, you WILL be doing 90+.
Passing a truck doing 5mph under the limit on the freeway? Move left, power gear, foot to the floor.
By the time you're past them with clearance to move to the right again, you're +20mph on the limit.
In regular street cruising, it badly wants you in 3rd gear. Third gear is DANGEROUS because it enters the groove around 45 and exits it around 90, and it's the gear where the turbo is most entertaining. So you can be cruising between stop lights and get a long series of greens and not-so-gradually amuse yourself with the bypass valve noise until suddenly you're doing 90 on surface streets after like 2 pulls. The car WANTS you to be a WRX Douchebag. It encourages it. Rewards it.
And lest you think I've taken the WRX douchebag life to heart, my corner of LA is *FULL* of the damned things. You'll see two or three street parked in any random neighborhood (every one of them either an STI or heavily modified). I was also the slowest one.
