You're engaging in a logical fallacy; have you considered that the people driving the new BMWs might consider themselves to be rich --or-- might nevertheless consider Bernie Sander's policy positions to be laudable?
Yes I have. If such people exist I doubt they make a statistically significant fraction among supporters of such policies. All Sanders supporters I know are both "rich" (i.e. can afford a new BMW or two) and do not believe that "the rich" to be taxed are them. These people are not really dumb so if they thought their own wealth needed redistribution they could figure easier ways to achieve that.
I don't see how.
