I don't understand taxis in NYC

Oh and since we were chatting about constantly being surprised by the financial privilege of coworkers, I’m flying away today! (Yay!)

I was trying to figure out what time I had to wake up to catch my flight.

Coworker: it takes 30 minutes to get to the airport.

Me: no, it takes about 45. I safely plan for an hour.

Coworker: for a taxi?

Me: a taxi costs a minimum of $48 to the airport, not including tax and tip. It ends up being like $60… The bus is $2.50.

Coworker: just take the taxi!

Me: … No.
