Years ago my rav had someone drive to his shul. He lived four miles away. He never told him it was ok, but he didn’t rebuke him or throw him out. Instead he welcomed him and concentrated on sharing the joy of Shabat.
After some time, the man stopped driving to shul and started riding a bicycle. This might actually have been mutar except that he lived outside the eruv. Again, my rav never told him it was ok, but he didn’t rebuke him or throw him out.
After some more time, the man stopped riding the bicycle to shul and started rollerblading. That might technically be mutar except that it isn’t exactly a Shabat-like activity. Again, my rav never told him it was ok, but he didn’t rebuke him or throw him out.
After some more time, the man stopped rollerblading and started waking the four miles. He didn’t do that for very long, though, as he sold his business and moved to Eretz Yisrael to learn in yeshiva full time. He still learns full time, years later.
I think my rav’s strategy may have been somewhat successful here.
