Actually, kind of a lot, thanks for asking.
He actively prevented Californians and Nevadans from getting realistic transit solutions by enticing government officials away from conventional rail and bus rapid transit solutions with unrealistic projects like Hyperloop and Boring Company, sending those citizens right back to the most expensive possible transit solution of buying his personal automobiles.
He fired thousands of federal workers through DOGE, taking salaries out of the economy that might have been spent on my business and directly endangering my safety by firing people inside the Federal Aviation Administration.
It's probable that his employees stole my personal data from the federal government (DOGE).
He is an illegal immigrant to the USA, since he worked on a student visa illegally, and therefore took resources that could have otherwise been allocated to US Citizens including myself.
He made the Nazi salute on national television twice, which was an active endorsement of violence against my ethnicity.
As a frequent walker and pedestrian, his Cybertruck is a massive and direct physical danger to me and more likely to kill me than other vehicles on the road. It is not legal to own in most/all countries outside the US as it does not meet pedestrian impact safety standards. Also, by all accounts the physical design was personally conceived and overseen by him.
His political views that parrot and support Russian talking points are a direct threat to the physical safety of people that matter to me in my life.
