And the use case is only for visual appeal? Good for those who need that. Probably can add advertisement on it to make it cheaper? I’m fine with normal looking one. Maybe it is beneficial, as it might reduce the performance at first but might keep temperatures lower and so increases efficiency again? Solar power is just great and it should get to a point where there is no more question about if it is worth it and will just get added to every roof that gets sun.
Bikes and Cars do not work well together. You will never have car free cities, even in small towns in EU, if you can’t drive around it with a faster road. Cities should not be build around important short and fast traffic roads, but that is how they are grown historical. Situation in rural areas is also very different to bigger cities. I would also say 30 is far from great for bikes. Most normal people drive slower and some drive faster. Speed is not the answer. Cars and bikes need different lanes. Everything longer than ~25km to work will be for cars or public transport. A good transition to having better transport will take a long time and reducing speeds to 30 is not a good solution.
30 is awful. I like 40 and 60 so much more. 30 might be still better than awful timed red lights.
The red light timings sometimes incentivizes to go faster as with 55-60km/h you can have a green wave and don’t need stop at any red light. for that it is totally worth it to drive faster. i hate when red light phase is longer than green phase. there are some really bad decisions on how red light timings work. Most do drive their path to work twice and know the timings and those do know when to drive faster/slower and will drive more aggressive to not wait at that one stupidly timed red light and have to wait and have like 25% more time to commute twice! (20->25min). It’s nice to calculate it with statistics but the way to work and back is better known and a slower driver might cause you to need to wait at multiple red lights while you could have driven a bit faster (and not always faster like in my first sentence but driving as fast as is allowed) and did not have to wait at any of that stupid red lights. I’m all for speed limits and better bike lanes etc. but driving slow when it’s stupid and stealing others precious time is fucking awful. What i also like are those that drive 60-70 constantly. Fuck man drive 100 if it is allowed and you can and drive 50 in the city but know, slow you down and than don’t even drive slower for the safety of entices in the city.
Isn’t Copenhagen and other bike friendly cities using bike lanes specifically to not have Bikes and Cars on the same lane? Cars are also great and super flexible, but cities should be designed in a way you can get easily from one to another by car, bus or train without needing to drive through other cities. For smaller cities it would be ideal to get to its outskirts with great and cheap parking places and can change to public transport or smaller things like bike or e-roller or similar. Historical grown cities and driveways have the drawback of having main roads and only connections going through areas they should not. There is a lot more to good traffic planning than not overtaking and reducing speed limits to 30.
