The classic British Routemaster double decker weighs 7.5 tonne and can be configured with 72 seats. Newer double deckers weigh 12.5 tonne and have a capacity of 60 seated and 20 standing.
Doubling the weight and doubling the wheel count leaves the axle weight unchanged.
> doing it at city bus speeds of under 10mph would be a catastrophic collapse in your standard of living.
LA average vehicle speed during rush hour is 27.6km/h (17 mph) according to Tom Tom [1]. So a 10 mph bus would turn that 27 minute journey into 46 minutes which I'll admit is more than desirable, hardly catastrophic though.
But remember that each bus can carry about fifty people which would remove close to fifty cars from the road resulting in less congestion and faster buses. Fifty cars need 400 m of road, one bus needs only 20 m.
And on your way home you can doze in your seat without causing an accident.
But let's suppose you are designing RoboVac vers. 1.0 OS, 1.0 OS does not use microphone, but one of our smart fellows wrote a document suggesting that we might want to have RoboVac be voice controlled! Maybe we can roll that out by 1.4, with some simple commands!! Let's put a Microphone in so we can add that feature later.
Later on you get fired, and smart fellow who wrote document gets fired, and OS 1.4 rolls out with spy tech to mark common product names and send them back to Amazon with your location data.
RoboVac 2.2 is out now, still no voice control, and you wonder why whenever you go to buy all your favorite products online there is 10% inflation on prices although news suggests inflation should actually be decreasing for the next half year.
otherwise is actually an accurate description of what -o actually means. It means do the thing on the left if it works, otherwise do the thing on the right. That is, if the clause on the left succeeds then the clause on the right will be ignored.
A naive interpretation of or in the light of Boolean algebra would be: do both and return true if either succeeds.
Wero is a long way from pan-European. It operates in three countries so far. We already have a similar thing in the Nordics (Denmark, Norway, Sweden, and Finland) called Vipps that uses one's phone number. You can also use it to pay in shops much as one uses Google Wallet or Apple. It's been in operation in Norway for over ten years.
Vipps MobilePay is already part of EPI's initiative towards pan-European cooperation, as well as Bancomat (Italy), Bizum (Spain), SIBS (Portugal).
Once Wero becomes usable in Austria, France, Germany, Benelux, and interoperable with those, the few remaining players will have a strong incentive to join.
