In my view, the first sentence isn’t long enough. Given the lad survived without, we presume, serious injury perhaps actually serving 12 months would be more appropriate, plus the removal of his licence for 10 or 15 years until he grows up - retest required before reissue. I generally do OK in N Yorks, by had a Velar pass to close in traffic today and a Golf on a clear road.
The second case is perhaps more like it - at least he got a ban. Again though, I’d be inclined to make it a bit longer and require retests at every category he wishes to drive, together with some sort of ongoing points system so employers and insurers know what they’re getting.
