Uber, backed by Goldman Sachs and BlackRock among others and valued at over $70 billion, has faced protests, bans and restrictions around the world as it challenges traditional operators and angers some unions. Uber has said it has also made significant changes to its leadership and has been proactively reporting serious incidents to the Metropolitan Police.
"I know we got things wrong and that we have more work to do".
Tom de la Mare QC, representing Uber, told Westminster Magistrates' Court the firm had taken the "unusual" stance of not opposing TfL's reasons for not renewing the licence.
Uber has been able to operate as normal in the city during the appeal process, and the firm could theoretically turn to higher courts if it is not satisfied with the outcome of this week's hearing. The case will be heard before the Westminster Magistrate's Court, and is expected to last three to four days.
At stake for the US firm is one of its most crucial foreign markets.
Since September's TfL decision, Uber has also been stripped of its licence by the southern coastal city of Brighton, in a decision which it is appealing, and the northern city of York.
To win its appeal, Uber will need to show that it's made substantial changes to its operation after a scandal-packed 2017 culminated in the company's founder and CEO Travis Kalanick being ousted and eventually replaced by the former CEO of Expedia, Dara Khosrowshahi.
It has however gained new licences in Sheffield, Cambridge, Nottingham and Leicester.
