  1. Indeed. There seems to be some credible suggestion that the Oxford/AZN press release glosses over some serious shortcomings in the trial protocols and it's even being mused that their vaccine may not get FDA approval for the States (which in turn would presumably cripple it for public acceptance and use in other territories, including maybe the UK. I hope that's not so, but this Wired article makes disturbing reading: https://www.wired.com/story/the-astrazeneca-covid-vaccine-data-isnt-up-to-snuff/
  2. Well the Oxford/AstraZeneca trial results released this morning and as usual the media seem unable to translate a press release into headlines without getting it wrong. BBC news was reporting "70% effective, single dose" which is nothing like what the AZN news release actually says. Actually both sub-samples on the trial used two jabs, a month apart, but one sub-sample was of a half-dose first jab. The sample sizes look to me to be way too small to say reliably that the 'low then high' dose regimen achieves 90% efficacy, although it probably is in that ball park. Still excellent news
  3. I read that's up to five days in fact (Pfizer spokesman, reported by Reuters). Nigel
  4. As EVs kick in for everyday use (which is a very good thing IMO) I am prepared to bet that interest in owning both classic ICE-powered cars and classic EV-retrofits like the lovely yellow TR6 in TRA issue 324 will grow and indeed their values will too. I say that because I think there is growing interest in all aspects of 'heritage', and as the world gets richer and people have more disposable income, the value of 'heritage assets' tends to increase. It may be confirmation bias on my part but in the last few years I've noticed growing interest in, and spending on, classic cars. Prices of
  5. It seems to make an appreciable difference. We've noted that that the meter reads 'long' for the first half hour in the morning before the tyres have warmed up. For that reason I've discovered it's important to run the measured distance twice, ie second time with warm tyres, rather than just once and adjusting off the first reading. Another source of meter shift is also of course varying degrees of wheelspin (assuming sensor is off a driven wheel or GB). On long gravel regularities - rare in Europe I guess but we certainly encountered every day on ERA NZ Classic back in Feb - we found it
  6. Jumping in on this... the issue is that ethylene glycol based antifreezes are highly toxic and (according to RSPCA and others) many cats die every year after ingesting it. Apparently it is sweet tasting but for whatever reason they will lap up small spills on a garage floor or driveway and it only takes a few ml to be potentially fatal. Some antifreeze brands are marketed as non- or low-toxic. Propylene glycol is one 'safe' chemical and I think that has been around for some years (used in aircraft de-icing?) but is less effective and more expensive than EG. I think some EG-based prod
  7. I think modern parking brakes are still electro-mechanical, rather than hydraulic - they either pull a cable or activate electric motors on the rear calipers. The MOT manual says: Electronic parking brakes must be maintained in operation by direct mechanical means, even though they are applied electronically. However, the mechanism for keeping the brakes applied is usually within brake calliper or motor gear assembly and therefore not easy to see. Hydraulic parking brakes as an only means of operation are not acceptable on vehicles first used on or after 1 January 1968. However
  8. I've seen at least one historic rally car (not a TR, an Alfa I think) with a 'switchable' hydraulic/cable handbrake so you can set it to cable for normal road use. But I'm not sure how that is contrived to work.
  9. I'd have to disagree on that, both for presidential and parliamentary democracies. The head of government's job is principally to lay out a broad agenda for government and to chair the cabinet (however that's termed), and in a presidential system also to decide when to exercise his/her veto on legislation. But I don't see some particular energy or faculty exclusive to relative youth being necessary for any of those functions. Good judgement is surely what counts? I'm sure we all know plenty of people in their 70s or even their 80s who are at the peak of their wits and abilities to make good de
  10. I liked the Ayrshire Daily News headline...
  11. A voting system and indeed a democracy is like a currency, it stands or falls on a consensus of trust. A currency can and usually will have a small degree of forgery going on and can easily withstand that. So can a voting system, provided people are confident that it's small scale enough so it doesn't really distort the result. I personally have no doubt that the US electoral system would stand up to that basis of scrutiny, simply because I've seen no credible reason to doubt it. In international rankings, the US electoral system consistently scores highly on the "free and fair" yardstick, eve
