I'd wager that at least 90% of voters do not do any research no matter their age and just vote for what the media or the people around them say.
Also.. I don't vote.
i also think there should be different classes of driving licenses with different speed limits, but now we're just indulging in crazytalk.
Different speed limits for different drivers could result in a "lower-class" driver being an obstruction for others. I don't think that would work out. That said, motorcycle licenses in the EU are separated into several classes with various maximum engine sizes (16+ for 11kW/15hp, 18+ for 35kW/47hp, and 20+ unlimited). They're separate tests.
what i'm really saying is that you should be able to test for a higher speed limit in the US. slow drivers will be slow regardless of what the limit is, and unsafe. i've driven on the autobahn in the no speed limit sections (primarily around munich) and there were still slower, unsafe morons occupying lanes they shouldn't have been. maybe tourists.
remember, in the US we have very low speed limits of ~100kph pretty much anywhere. i think it should be higher. people routinely drive 145kph here in southern california, enforcement of 100kph is arbitrary, which is not healtyh for respect for the law in general.
I've driven in both Germany and the US (DC area, while on holiday), and found US driving a lot more relaxed. There are some odd rules here and there, but in general it was less unpleasant. Driving on the Autobahn can be quite stressful when you have a few people who want to drive really fast. Those kinds of speed differences reduce road capacity significantly. I'm not saying these people are necessarily unqualified to drive at such speeds, they may be the best drivers in the world, but everyone would reach their destination sooner if those folks were to stick to 130-140km/h.
That said, the posted speed limits in the US are definitely on the low side. The same roads would have a higher speed limit in Germany.
This sounds quite interesting, actually.
I wonder what the consequences would be if e.g. only grandparents have the right to vote.
How that works is pretty simple. Here is the short version:
Instead of one party (like democrats or republicans) winning each state, we have 3 elections each election. 1 election for each municipality, one for each county and one nation wide. The percentage of each is seperate and decides how much deciding power (seats) you will get in each instance. Since Sweden is pretty much ruled by each municipality governed by the country laws (essentially made by Riksdagen) you can retain some power in a municipality or county even if you don't get that many seats in Riksdagen.
This creates some interesting scenarios, since I can vote for a tax-lowering party in my municipality but vote on a completely different party in the nation wide election. For example, I may want to reduce Swedens immigration and can thus vote for such party to Riksdagen that maybe have more socially goals for the society.
But in a sense, yes, as long as direct democracy isn't a thing your specific voice won't be heard.
