Uber and Lyft are on the same side on this issue: They vow to leave Austin if voters in Texas' capital city fail to overturn a proposal requiring drivers to be fingerprinted.
With Proposition 1, Austin voters will decide on Saturday, whether to require ride-hailing companies to conduct fingerprint background checks for their drivers.
The two companies have spent millions of dollars trying to convince voters that the measure is unnecessary, and that the companies' current background checks are more than adequate. Austin is the first U.S. city to hold a public vote on fingerprinting-ride-share legislation.
The ride services have come under increased pressure about background checks after an Uber driver in Kalamazoo, Michigan, was accused of going on a deadly shooting spree in February.
The City Council passed an ordinance in December requiring drivers for ride-hailing services to undergo fingerprint-based background checks. This was met with opposition from Ridesharing Works for Austin, the political action committee largely funded by Uber and Lyft, which gathered enough signatures to force adoption a weaker ordinance or a vote.
