So Why Doesnt the Gas Cap Open Instantly?
Probably something that I will just have to take it as it is, but I am really curious why the gas cover does not open instantly and I have to watch the little status meter on the dash.
Its just so weird and foreign to me. I wonder what exactly is the purpose of this and how it affects the emissions control. Is this only on the hybrid or also on the regular RX?

From the RX450h Emergency Response Guide:
The RX 450h has a fuel vapor containment system that results in the tank pressure being higher than that of a conventional vehicle. If the fuel filler cap is removed after using the manual fuel door release, the vehicle will not automatically reduce the fuel tank pressure. Opening the fuel cap in this state will allow pressurized fuel vapors to escape, and fuel may also be discharged from the filler inlet. For these reasons, be extremely careful and open the fuel cap slowly.
