Reports claim Waymo has about 373 drivers in its roster, nearly four times more than Apple's recently expanded crew, while GM-owned Cruise has 102 state-certified drivers. As Apple Insider notes, Waymo has 615 cars in-field testing, while GM's Cruise division has 201 vehicles involved in self-driving car testing.
Unlike GM, Apple does not build cars, and it is unclear what the American technology corporation will do with its self-driving car tech. Rumors about a car from Apple appeared back in 2014, and its Project Titan had over 1,000 employees until late 2016 when company executives decided to cut back the team.
If Apple does decide to sell a car that drives itself, the company would have to partner with an automaker to enable it to develop a vehicle within a reasonable time. Hyundai was one of the brands that were involved in negotiating with Apple for the manufacturing part of the alleged Apple car, but the deal fell through.
With no official partnership with a manufacturer, Apple is left with buying vehicles from whatever automakers it chooses until the company develops a fully functional self-driving car technology. Some believe that Tesla would be the best partner for the role, but the two companies did not share the same vision.
Apple's self-driving car project was not left ignored by competitors in its field, as tech giants like Xiaomi and Huawei have announced similar plans.
