Summary: Method written to separate untested functionality from the original
send method. If the stream is valid, it gets sent to the car. If not,

null is handled by the car.(?)
Pre-condition:
sendValid receives a stream.
Post-condition:
Either the original stream is sent, or the car receives a stream of
value null.
tc0: The stream is corrupt
tc1: The stream is empty
tc2: The stream is valid
