Play the whole Half-Life 2 campaign and swap to a Rocket League car any time: boost, flips, wall rides and supersonic demos on the Combine.
Play the whole Half-Life 2 campaign, and press V (controller: Back) at any moment to swap Gordon Freeman for a car that drives exactly like Rocket League's.
Everything is normal Half-Life 2. Doors, buttons, ladders, pickups and weapons need Gordon, so hop out when the story asks for it.

On foot, every key and button does what it always does in Half-Life 2. Everything can be rebound in Options > Keyboard (the Fennec entries).
