It’s perfectly happy running on devices without gps, so it’d be a maybe nice to have but not a thing the project could rely on to meet regulatory frequency compliance.

For your motorcycle use case, keep in mind this is a small group of people mesh thing, not something where one device can expect to connect to unknown other people. The SPOT tracker is still the solution you want if you’re looking for safety/emergency contact.

What meshtastic might be useful for on motorcycles (and I’m considering building some of these) is a medium range mesh network between you and your riding group, with super simple super limited Comms UI. I’m thinking 3 or 4 different colour old school video game type buttons that you can mash wearing gloves, that light up a bright-enough rgb led to see in the sun, with 3 or 4 agreed meanings for the colours. “Pull over and check messages”, “Wait for me”, “I’ve crashed”, “Cops!” type messages, that can be sent/understood without needing to read a text message on a phone screen (but still having that text messaging available as well).
