The thing is: They don't NEED to handle stressful situations. GridGuide can handle that. Also, 'a stressful situation' can just be a reduced threshold. And nothing is stopping you from getting a better car. You want Handling 1? Invest in it.
Sure, GridGuide keeps anyone from needing to make control rolls. But I'm not complaining about the low skills and reactions of modern drivers, I'm complaining that a skilled driver in a normal vehicle will likely crash in very normal situations. Let's just say you have a pilot pool of 9 dice, say 4 attribute (a well above average reaction rating) and a skill of 5, which is described as "Advanced professional: Even other pros realize that you've raised your game, and if they hustle you'll leave them behind"
For some common vehicles, here are the speeds at which control tests would, on average, be failed:
Harley-Davidson Scorpion: 31 km/h
Suzuki Mirage: 61 km/h
Ford Americar: 0* km/h
Hundai Shin-hyung: 26 km/h
Eurocar Westwind: 61 km/h
Misubishi Nightsky: 0* km/h
Every truck and van: 0* km/h
* obviously a control test at 0km/h isn't likely, but the point is "unsafe at any speed." A rather competent driver will on average fail their control test in any circumstances in which they have to make it, and then on average will fail the test to avoid crashing.
Also not a single drone in the CRB would, on average, succeed a control test while running autopilot (at pilot*2 dice pool)
Given that math, I would not ask any player to use the control rules as written, as they just don't generate sensible results.
