Why would you get into a car with that driver? Out of the total population of licensed drivers in the United States[1], about 1% have DWI in any given year and the recidivism rate is upwards of 20% depending on the state[2][3]. Given available statistics about the relationship between alcohol consumption and likelihood of a vehicular accident[4], there's good evidence that you're increasing your risk of being in an accident by at least 60% if you get into a car with someone who has had a DWI.
Further, considering recidivism can only be tracked if people are caught and the legal limit is 0.08 BAC, a good argument can be made that an Uber driver with a past DWI would be more likely than can be predicted to have be driving under the influence again (meanwhile a BAC of 0.05 still increases the risk of an accident by approximately 100%).
