the most insane part about that crossing was that it was considered so dangerous and the voltage shifting so delicate that a permanently manned switching house was required (on the left) and they even installed barriers for trams
Any of you bros ever gotten melanoma before from riding out in the sun for too long?
The reason I ask is because I might of fucked myself by riding without applying enough sun screen this past summer - now I have a small mole on the side of my neck the itches like fuck. I plan on having it checked by a doctor tomorrow morning. Damn.
>>912648 Really dumb. People aren't buying into the "self-driving car" thing, so why would they hop into an AAV? A car is one thing; if the computer driving the thing has a brain fart the driver can take over, this thing has no flight controls. Even if it did, roughly 1/2 of 1% of the American population is a pilot of any stripes, so the other 99.5% would be useless in the event of an emergency. There's a reason the military isn't letting optionally-piloted aircraft run any sort of troop transport or... Comment too long. Click here to view the full text.

This is called EHang 184. It flies for twenty-something minutes, using (presumably) electric motors. Besides flying autonomously, it's also going to be constantly connected to a control center that would be able help if something goes wrong.

I heard the EPA refused to issue new water permits due to pollution. The only way to get a water permit was to destroy an older building and take that permit. That's why so much of Houston looks like a post-apocalyptic wasteland. Is this true?
I want a non-carbon road bike. How concerned about rusting a steel frame do I have to be if I want to wash it with a hose in my yard and stuff? I'm considering getting a stainless steel or titanium frame as I'm worried about corrosion.
>>912069 Corrosion happens when water sits in contact with steel for a long time, much quicker if there's salt dissolved in the water - so washing a steel frame with water is fine as long as it can dry completely after cleaning, and you avoid spraying water into the frame where it can be trapped and form a permanent pool. If you live near an ocean, or somewhere where salt is regularly applied to the roads, you can still use an ordinary steel frame, but in that case it's a good idea to use a rust inhibitor (framesaver)...

this is not a bike question in general, but I didn't want to start a own thread. I really like to build bikes. I kind of can't stop myselfe from doing it. what's the best way to turn this into a sort of side buissness. where is a good place to sell custom bikes and such ?

For the benefit of the other readers of /n/ who may have difficulty understanding OP's meaning, allow me to translate; >I got a cargo bike and I was riding it and some random girl on the street that I don't know smiled at me (reason: unknown) to which I mumbed "Y-y-y-you t-t-too" and just kept pedaling, so now in my own mind I think girls like guys on cargo bikes.

What's a good front and back light for my bicycle and why? I've used a Sigma for 8 years now and the battery pack only lasts for like 30 minutes anymore. When reading about some lights, there's no light that seems to be really fine. They all seem to be trash or maybe I'm just looking in the wrong direction. Also I don't need to see 10000 meters ahead, I just need to be seen on the streets. I'm willing to spend a decent amount of money on it.
NiteRider's combos are all you need for typical utility cycling. Their rear light is the best I've ever encountered. The front light's battery life is merely passable, so I would recommend getting a higher powered model and running it on a lower setting for more endurance. 200 lm is sufficient for road riding, though on unlit roads more illumination may be useful.
I would also recommend showing at least two lights to the rear, for the purposes of redundancy.
>>911952 I'd suggest whatever super China lights you can get on ebay or at a hardware store. In my experience, its better to consider lights as a consumable, either because they break, get lost, or stolen. I work with a cat eye rear reflector light, and a CREE LED light and a battery pack. Cost about 60 bucks all together.

>>909459 There are many poor deluded souls on this board, most of them young, who think that all the world's problems can be solved by eliminating motor vehicles from it. Of course they're blind to the fact that they wouldn't have bikes to ride or any of the modern conveniences (including the computer and the Internet they're using to complain about the evils of cars and the people who own and operate them) without motor vehicles; the majority of us would still be living in rural areas, and rarely see cities...

>>912422 thanks, i see. coaster brakes have a larger diameter than a standard hub.
I had regular spokes and rims for a road bike, nothing special, the problem might be that they are not adjusted well, I've been to two different bike repair shops, but after both have adjusted them on two separate bikes they keep breaking,. At the moment I have two broken spokes.
I'm not fat, weigh about 70 kg, not super strong either. I might start adjusting the spokes myself, try to find an instruction video

Ex-Amish truck driver destroys historic bridge by driving her 30-ton trailer across it - because she got her math wrong and didn't know she was FIVE TIMES over the weight limit

Lambright, of Fredericksburg, told police she knew the iron bridge had a weight limit of six tons and wasn't equipped for semis due to a sign that was posted, but said she didn't know how many pounds were in six tons.
Lambright and her 17-year-old cousin who was in the passenger seat managed to escape unharmed.
