Err… Is your team doing planning during standup? I’ve never heard of that, from either people who are on teams that use standups, or from any of the Agile/Scrum literature that I’ve seen. In my experience, standups are typically about either a) coordinating the execution of work that has already been committed to, or b) whoops just a status meeting and everybody’s tuned out.
And being on a track in a controlled environment. Going anywhere near this speed on a shared road is absolutely unconscionable in any conditions.
