Lines 33 to 35 in 6b80776

	vehicle: {
	id: event.id,

Add two fields based on existing vehicle metadata available in the API

Also in

Add:

• occupancyStatus

as per event.occupancy_status, but the strings used are not entirely compatible with api, but should be event.occupancy_status for most reasonable values.
