Add an option to email reporting user for more details when creating the report. The long press on report currently gives options for Police, Hazard and Traffic. My suggestion is to add one for 'email me' where the user can provide full details when they are not driving. Navigating to the Report, finding the correct option, before finding the Later option is not safe when you driving.

As editors, there are a lot of reports with minimal detail. Posting a request for the submitter to provide more details rarely gets a response.
