Convincing the transit-averse?

My wife and I had a day out planned in Dallas. Yes, I know, please hold off on comments about how sucky Texas is, I can't help it (I don't disagree, but this is where i am for now), my job is here but we hope to move elsewhere in the next few years. Possibly to either Toronto if we can get PR approval or otherwise to Portland or Denver.

Brunch at a little bistro on Harwood. Dallas Museum of Art or Nasher Sculpture Center. Then a bit of window shopping and exploration in Bishop Arts followed by a show at Texas Theatre.

I had planned to drive in from Denton, park downtown, and then use the green or blue line to Union Station and then the Dallas Streetcar to Bishop. Easy peasy. A few bucks each for fare once we'd parked and about a 40 minute light rail and streetcar trip with maybe 10 minutes of walking total.

She got cold feet about it. Something about how "we don't do that here. It feels wrong." So we ended up back in the car and paying for more parking.

We've traveled other places where we got from point to point by rail. Toronto. New York. Even to a degree in Las Vegas with the monorail. But for some reason she couldn't bring herself to use public transit at home.

What to do to make it more appealing? I already drive an EV, so gas savings isn't as big of a concern.
