have you considered MQTT? You could setup the MQTT WeeWX Extension in which it will push both LOOP and ARCHIVE records to a MQTT broker. I have an Acurite 5-n-1 weather station and use MQTT to update my website as the LOOP data changes. I get updates around every 18 seconds or so.
In your Python program, you use Paho Python library to "subscribe" to your MQTT host and invoke an event when you get a LOOP Record. From there evaluate the rain values and take action with your car windows at that moment based on the data. MQTT is a small, lightweight protocol that will update in near real time. It is used a lot in IOT devices.
