My feelings on Uber are complicated (though, getting less complicated every day). Where I'm living now (San Jose, Costa Rica), there's scheduled to be a large taxi strike tomorrow that will likely cripple the entire city. They are protesting Uber siphoning off their business. But, the taxi drivers are not making any friends doing this.
I feel bad for the taxi drivers. I do. But, the prices to take an Uber are literally (not figuratively) half and the service is way better. The drivers that I speak with typically Uber as a secondary source of income and are generally pleased with it.
I know this comment is a bit off topic for this thread, but the question of whether or not to Uber in Costa Rica has been answered. Answered, at least until another competitor enters the market. I wouldn't be so fast to short the company.
