WTF is a professional camera anyway, is it the one I'm using to take the shot? No need to answer that.
I use Fuji professionally and have done for the last few years, haven't experienced any lockups (well one but that was a dodgy 3rd party battery and not the camera). I have read that some others have alright, with the X-T2 and X-H1 but I mostly shoot with X-PRO2's so nothing bad there.
I've found Fuji to be spot on consistent shoot after shoot, there is no way I'd risk ruining a shoot for a client because I thought the camera is not going to preform and the client doesn't care about the camera used anyway, not that they'll ever know what camera unless I bill out something to them. The DR of the camera is clearly up there, within half a stop of a Sony's 135 sensor - that's amazing but still they are all piddly when you plonk down a proper full frame camera and work those images up

I do love all this comparing Fuji with their little sensor to the bigger 135 ones. Says a lot to me but I couldn't watch that vid - I hate those comparisons.
As for shooting cars at night with Fuji I think if you go look at a how a professional photographer manages to get the shots at night that be of benefit to you. You know the kind who uses his Fuji cameras to produce the official imagery for one of the worlds biggest night time races, races that cost millions to run a car in. So I guess Fuji can do the job there or perhaps it's the photographer and he is just risking his contract be shooting with a hobbist camera system... either way the shots look amazing.
I'm [extra] grumpy today as the roof of my office collapsed yesterday & now it's raining and the weekend and I'm having to work at home and the kids are running about. Least my lovely wife just placed some beer down in front of me. No gear damage thankfully as it was all cased up and the roofed missed it somehow. Sigh.
I wonder the same thing every time I see something labeled as "professional"...
Damn, sorry to hear about your roof...
