The emissions part I'll have to agree on, but safety? Germany is literally among the safest nations to drive in. There's not much lower you can go.
As ICE vehicles get phased out, people will naturally start driving fast less often. EVs force you to stop for much longer when you run out of charge. Driving 2x as fast means making 4x as many stops and the stops aren't 3 minutes with an EV.
I think you're only supposed to add up the agree and disagree, and the strongly and somewhat are subcategories that are shown separately of the main categories.
Bad data representation, but not outright lying here. Where the lie comes in is that you had to be a Trump supporter to even vote. It's based on CPAC attenders, aka politically active MAGAs. The 1% that disagree he's doing a great job probably want him to be doing more of his bs.
