Of course multi-crew flying, correctly organised and trained, is safer, and I like it when I do fly with another pilot. However that really is off topic, as the discussion here is about single-crew IFR as a safe form of transport in itself, not as a comparrison with multi-crew. That multi-crew is even safer does not mean that single-crew IFR is inherently unsafe!
I would agree also that I want an autopilot, of course I cannot fly public-transport without it, but again that is off-topic because I don't just fly familiar, short routes. If I was doing then the autopilot becomes a lot less relevant. The CAA recognises this.
