> but something like a planter, another car, a curb, a tree, the front of a 7-elevn etc. is going to stand a much better chance of stopping a smart car than it is a 4,900 + lb. F-150 that carries its weight up high.
This is another area where looks can be deceiving. Those large vehicles also have large frontal areas and large crumple zones to absorb impacts.
Those small smart cars have small frontal areas and relatively rigid frames because they can’t crumple on impact.
It’s not hard to imagine scenarios where a small, narrow smart car would literally slip between obstacles where a larger vehicle would get hung up on them. This is especially true for typical bollard spacing.

I think you’re overestimating the difference it would make. Like I said above, the smaller area of a smart car makes it less likely to actually catch the tree (by definition) and the relatively rigid frame isn’t doing much to dissipate the energy it’s carrying.
Looks can be deceiving. I know everyone wants to believe smart cars are super safe alternatives, but any of these thousand pound vehicles isn’t going to be good to go up against. The differences are more nuanced than your eyes would tell you.
