You might want to have tubes with both Presta and Schrader valves (to match the existing tube on the other tire). Theoretically you could use either, but some rims might have a hole that's only small enough for a Presta valve (so I guess that makes Presta slightly more compatible in an emergency!).
I agree that there's flexibility in the sizes. When I wanted to stock up my work's garage with spare bike tires, I got four kinds in total (basically a small Presta, a small Schrader, a large Presta, and a large Schrader). This officially covered pretty much every common road and hybrid or mountain bike with something that was officially rated or matched to it. But yes, as far as I know, one could probably get by in practice with fewer than that and use things that are officially slightly mismatched.
Specifically, I got the Specialized "Standard Schrader" 700x20-28c and 700x28-38c, and "Standard Presta" 700x20-28c and 700x28-38c tubes (the smaller ones more likely for road bikes, the larger ones more likely for mountain bikes). These are about $8 each in the U.S., so a total of about $32 for the set of four. 700c is increasingly common, although there are several other diameters that have been or are being used.
Just having a bike pump can be pretty helpful in many circumstances!
I too am irritated by their software but they do make nice hardware. I’d have their headphones if I trusted their software, the hardware is perfect IMO. Open and upgradable is not really their forte though.
I’ve found “Increase Contrast” to be a better setting. Still a little bit of transparency but most elements now have borders and much more readable text. Not too many rough edges.
Yeah I’ve just set any search starting with !m to redirect to google maps. It’s in the custom search settings somewhere.
I also find Kagi good in the UK - it wasn’t amazing when I first subscribed but got a lot better quite fast. I do occasionally add “uk” to a search when shopping but I did that on Google too.
A camera is no substitute for actual visibility, at best it’s a mediocre workaround to the problem. There is no evidence at all that I’ve seen that there are fewer pedestrian collisions in modern large vehicles - I would be interested if you have any such data.
Regardless, all of these “extreme measures” could be applied to a smaller car (or even just one with a smaller wall at the front) for the best of both worlds. And collisions will happen regardless, sensors and cameras are not a magic solution.
> I mean, the risk was already socially acceptable
What society considers acceptable changes over time. Just because it was socially acceptable, doesn’t mean we continue to accept it forever. Don’t forget slavery, the idea of women as chattel, kings as having a god given right to rule etc etc were all “socially accepted” once upon a time. I doubt you would advocate for a return to medieval times on the basis that it was “socially accepted”.
> it has further been reduced as far as practicable.
This is obviously untrue. Car safety for drivers and pedestrians has continued to improve year-over-year (except in the U.S., where pedestrian safety has got worse). There’s no reason to believe the trend toward increased safety is suddenly going to halt now.
> I dont even know what point you are trying to make here. Seeing things a different way is not seeing things? Make it make sense.
Obviously, last I checked I spent my time looking out of the windscreen of my car when driving, not staring at a screen in the centre console. Being able to see everything by looking an out of a single window is always going to be better than having to swap between looking out the window, and looking down at a screen.
Not sure I completely agree (if the definition of vehicles is cars). That disregards miles travelled by cyclists and pedestrians etc. If 10% of the population switched from driving to cycling to work but the death numbers stayed the same, that metric would go up but really nothing would have changed, either mortality wise or in terms of number of people using the roads.
There’s a lot of research that for the average person, getting an e-bike will result in more exercise than a normal bike. Not because you work harder on one but because you’ll use it more. My knee jerk reaction was the same as yours but I’ve changed my mind on it.
Yeah, in the US they should probably run overhead wires which would be more efficient than batteries. They could also consider coupling together a few dozen trucks on the highway. For the ultimate in efficiency, and to reduce particulate emissions, they could replace the wheels with steel wheels and make them run on tracks...
Running overhead wires cross country in the US would be exorbitantly expensive. In the city? Sure, though it would be ugly. In the countryside, not a chance of it being workable.
You don't need it in the city or in the countryside, you just need it on the highways. The overhead wires will directly power the cross-country legs, a small battery can cover last-mile delivery and interruptions in overhead wire coverage due to things like complex highway interchanges.
Besides, it's not like this kind of electrification is unheard of. Most of the world has electrified rail with a density higher than the US highway system, and India has been electrifying its railways at a pace of over 4000 miles per year. Electrifying the main cross-country freight corridors by the end of the decade should be quite doable.
Electrifying railways seems easier than doing it to the US Interstate, since the railways control what goes on their tracks. The US has roughly 50K miles of Interstate highway. From what a cursory search showed, electrifying rail is roughly $1m/mile. So it would cost at least $50B to electrify, not to mention converting the semi trucks to use it. Considering how much of a hot topic EVs and alternative energy sources are, this is a non-starter in our current political climate.
And forgetting the practical components, the highways would look really bad with wires overhead...
Who said anything about long haul? A longer workday doesn't mean a longer route. Most trucks do multiple deliveries every day without ever leaving their home area, commonly between ports and warehouses.
