Technically, I could probably get away with that, but I'm based in East London and have over a dozen supermarkets within 1-2 mile radius, so barely worth getting geared up for. Travelling further would be taking the piss slightly.
I'm also very conscious as to how overstretched the NHS is currently. Word from the front line is not good, all the shit political short term thinking from last couple of decades is coming home to roost. From chronic underfunding, charging tuition fees for nursing degrees, pay-freezes, anti-immigration policies, bit-wise privatisation of services, crap IT systems, private firms crippling trusts with service debts for new hospitals etc. Successive governments have sent the NHS into a downward spiral of failure, setting things up to make wholesale privatisation appear a better choice. All of which has left the NHS simply unable to cope with the current number of admissions.
Last thing I want is pop out on the bike, to find myself in some minor collision with some East London numpty driver, then stuck on side of road with just some broken bones wondering if I'm gonna get an ambulance to a hospital, whether I'll get a bed in a non-covid ward, or any bed for that matter, and then if I'll be picking up a nice covid souvenir to complement my asthma. And what for? A quick ride in some shit weather to pick up some milk. No thanks, best plan right now, is just sit tight, stay away from everybody, avoid any further strain on the NHS and await the vaccine rollout.
We'll be biking again in a few months, recent lockdown delays will probably mean it'll get worse before it gets better, but we'll get through it. It'll be better weather by then too.
