I don't think he was in hospital enough even for automatic suspension!
A bit of a tangent but would not an admission to hospital with chest pains amount to an immediate grounding?
As he says, the way we avoid collisions is to shove everybody into a ten mile wide corridor............
You forgot the 2nd part: they then spend £££££looooads on an ATC system to keep them separated
I've had a few close shaves with traffic; maybe 50m. For me, the general idea is to get away from the circuit with maximum haste, spend the minimum time in it, and if it is busy with half a dozen "in the circuit" I come back 15 mins later.
Enroute, OCAS, I fly at "funny" altitutes like 3300ft, 3700ft, 4300ft, 4700ft, etc, never below 2000ft, always VMC on top if CAS permits (almost never seen any GA up there). There is a massive increase in traffic density below about 1500ft AGL and this is reflected in the UK midair stats.
I also rarely fly at night - something governed by my base's closing time which is too early for most of the year to log night time.
