They are often still offered as benefits to the employee.
Offering Waymo and taxis as "commuter" benefits (meaning, to/from the employee's home) to the employee is considered taxable income to the employee unless it's used so rarely that it is considered a nontaxable fringe benefit.
As this creates payroll headaches, most companies outside of perhaps a few in the Bay Area do not offer Waymo or taxis or black car services or Uber/Lyft as "benefits" to the employee.
This is different from the kind of travel costs that can be expensed by employees (i.e., for business trips, client meetings, etc.).
