For some it may be hard to recognize the Sonic logo not lit up in neon. Sonic's neon sign is a signals that sustenance is on the horizon. A sight for sore eyes on a long drive.
Look how much better this sign looks in neon. This is true Americana.
The new logo is keeping the shape but moving away from its neon heritage and more towards a more of a bowtie look then two arrows. This is an interesting choice for a fast food restaurant.
