Goofs

In the scene after Poppy has aborted her lessons for good with Scott, she walks past the same row of shops twice.

Poppy cycles South of the river over Blackfriars Bridge but gets off in postcode EC1 (shown on a road sign), which is north of the river. A minute later, when she walks into a shop, she's in SE1 - which is where she should have ended up.

In the build up to the final (aborted) driving lesson Scott (Eddie Marsan) is seen turning right into Holloway road (half way up and heading north), then moments later they are seen navigating the Highbury and Islington roundabout, turning into again into Holloway road about half a mile south of the previous location.

At one point Scott admonishes Poppy and asks her how old she is. Poppy replies she is 30. Scott would have known Poppy's age as he inspected her provisional driving license at the beginning of their first driving lesson. Towards the end of the film Poppy's age comes up again when Scott guesses that she is 22 when, as previously explained, he would have been fully aware of her age. The latter incident could have been deliberate flattery on the part of Scott.
