A few comments, a creative approach to organizing the data, but a little difficult to maintain.
| i = 0 | ||
| drivers = [ # drivers array | ||
| #index 0 of drivers array | ||
| driver1 = { |

You don't need things like this driver1 = { here.
I also think making these internal hashes containing 3 arrays, rather awkward to traverse. It's also problematic if you accidentally add an element to one array and not the others, they become out of synch.
I would suggest instead doing something like:
driver = [
{RD0073: [
{ride_id: "RD0003", rating: 3, pay: 10, dates_active: "2016-02-03"},
{ride_id: "RD0004", rating: 4, pay: 12, dates_active: "2016-02-07"}
]
}
] That makes it easier to loop through things and keeps trips together logically.
| drivers.each do |driver| | ||
| i += 1 | ||
| puts "Driver#{i} pay: $#{driver[:pay].sum} for #{driver[:ride_id].length} rides." #calculating pay and ride number | ||
| puts "Driver#{i}'s average rating is #{(driver[:rating].inject(0.0) { |sum, el| sum + el } / driver[:rating].size).round(2) |

Nice work using an enumerable (inject) to sum up the pay.
Also good work using round.
