The incident was reported to police, but a spokeswoman said the lack of any evidence at the scene meant the matter had been filed.
Hall alleged the abuse had continued this weekend with an incident at a taxi rank on Saturday night, and she had also been bullied on social media sober-driving pages, she said.
Hall claimed she had everything required to legally operate a taxi service, including her small passenger service licence, passenger endorsement, in-car camera and current certificate of fitness.
The Otago Daily Times has verified with the New Zealand Transport Agency (NZTA) that Hall and her car meet all legal taxi requirements.
Dunedin City Council group manager transport Richard Saunders said as long as Hall had a small passenger service licence, she was able to operate from city taxi stands.
The ODT understands some criticism of Hall's service stems from the fact her car lacks roof signage. However, the NZTA last year removed requirements for this.
Southern Taxis Dunedin owner Anthony "Starskey" Ware suggested Hall should start operating under the banner of an established taxi company.
"If she wants to be a taxi driver, join a taxi company."
While he did not think any "legitimate" drivers would have intimidated Hall or attacked her car, he would not put it past "pirate taxis", operating independently of companies.
