SAN FRANCISCO (Reuters) -The CEO of Cruise, General Motors' robot taxi unit, on Saturday apologized for the company's situation following an accident that led to the pause of its self-driving vehicle operations while it conducts a safety review. In an email to staff reviewed by Reuters, Cruise CEO Kyle Vogt also said the firm would make a new tender offer to allow employees to sell shares, just two days after cancelling an earlier offer. "I am sorry we have veered off course under my leadership and that this has affected many Cruisers in a deeply personal way," wrote Vogt in the email to employees.
