Let’s just start with the fact that American political system is super skewed to begin with and no actual left has any power.
Dems are highly pro-capitalist, moderately nationalist and merely call to strike a bit less horrible balance between the interests of people and businesses. This is not left, this is a bit better right.
This fallacy keeps people trapped in an idea that the only possible options are “good” ultra-capitalism and “greedy” ultra-capitalism, which is not true.
People that try to have “both sides heard” totally ignore that there are way more than two angles in this conversation and that Dems are not some sort of a political extreme. Reps, ironically, kinda are.
And Democrats often think they vote for something actually good, when it’s actually just a lesser evil. Keep that in mind, no matter what you decide.
Solar panels are very cheap, and any modification, even just a moving cover, greatly ramps up prices. No, really.
We just need a lot of panels to generate significant amounts of electricity, which would necessitate a large cover or a lot of mechanisms - which would get expensive on that scale.
As pointed out already, acceleration here is massive, as collision takes split seconds.
A more useful formula is: F=m*∆V^2 /2, where F is the force, m is mass, ∆V is speed difference (essentially your entire speed if you’re gonna hit the wall, and that’s very likely).
Notice that speed in this formula is squared, so doubling the speed results in four times the impact.
22% higher speed leads to 50% higher impact.
41% higher speed doubles the impact energy.
Etc. etc.
Also, mass of your car, even though it’s not squared, impacts the result greatly. Twice as heavy car will exert twice the energy at the same speed.
