I think your player may be confusing AR and VR.
AR is described on page 229 as being "normal living in physical space with an AR heads-up display". You only take a -2 penalty to Perception tests in AR "if your attention is really focused on your AR display and not your surroundings", and even then it's up to the GM.
VR is also described (page 229 for cold sim and 230 for hot-sim), and in this mode your body goes limp and you're completely immersed. Hot-sim VR provides a +2 dice pool bonus to all Matrix actions (which includes Control Device).
Your player can operate vehicles according to the three (four) individual methods on page 265; manual control, remote control, rigger control, and autopilot.
Of these methods, manual and remote control can both be done in AR, while remote control and rigger control can be done in VR. Note that rigger control (aka Jumped In) requires VR, and cannot be done in any other way.
So, with the above information, we see that the rigger can in fact operate a vehicle with manual or remote control just fine without AR gloves; as long as the character has a means of obtaining AR (and AR gloves does not really add to anything game mechanics wise), the character gains benefits as described on page 201.
[EDIT]
Forgot to mention the most important thing; since AR is considered always on as long as you have the components for it, you'll never need to take an action to drop "into" AR. It sure sounds to me like your player is confusing AR and VR, as it's entirely possible to control a device in AR without penalties, and it is only VR that requires the "Switch Interface Mode" action as listed on page 243.
