Pretty normal here in the San Francisco / Silicon Valley area. Although it usually comes in the form of chartered busses, transit passes or free parking. And parking in San Francisco can be like $400 a month, so free parking is nice.
The commute in this area averages 1-2 hours one way for many. So transportation perks are important to retaining high value employees.
And because the commute sucks, remote / hybrid work options are also key for many gigs.
