I dont think you can create a high trust society deliberately; It takes multi-generation level time-spans, and in a low trust environment there is no mechanism to guarantee your plans will be carried forward; even if you currently have dictator level control over society.

Creating highly trustworthy technology is the best we can do, and reliable transportation is a big part of this.

I also suspect targeting and removing the worst interactions people have with strangers (and for many this is the random nature of a human driver, either from a taxi or other drivers) would create a higher trust society overall, as there is less cause to be wary.
