Ground vehicles don't, as a rule, use ICAO callsigns/designators (since many of them don't belong to airlines) and the types of transmissions they make are unlikely to be confused with those from live aircraft, so there aren't really any safety implications.
Heathrow clearly agree and hence allow its continued use.
