Dramatic footage of a vehicle on the wrong side of the road near an RAF base has prompted police discussions at the "highest level" in light of the death of Harry Dunn in a separate incident nearby.
The video, reported to Northamptonshire Police on Saturday, shows a blue BMW having to brake sharply on a country road near RAF Croughton.
A force spokesman said Chief Constable Nick Adderley had personally taken control of the incident "in light of the ongoing investigation in Northamptonshire".

RAF Croughton became the focus of an international controversy after Mr Dunn was killed in a head-on collision with a car yards away on August 27 last year.
Anne Sacoolas, 42, the wife of a US intelligence official, claimed diplomatic immunity after the collision and was able to return to her home country.
The US State Department said a UK extradition request for Mrs Sacoolas was highly inappropriate and would be an abuse.
Before reports of the latest incident surfaced, Business Secretary Andrea Leadsom, the constituency MP for Mr Dunn's family, wrote to the commander of the base to ask for an invitation to visit.
Mr Dunn's mother Charlotte Charles and father Tim Dunn are looking for assurances that safety measures are in place to make sure there are no similar incidents in the future.
Confirming the force had been given the footage, a spokesman said: "We can confirm we have received a report of this incident.
"It falls in the Thames Valley area, but the Chief Constable (of Northamptonshire Police) has seen the footage.
"The incident is currently being discussed at the highest level in light of the ongoing investigation in Northamptonshire."
Dunn family spokesman Radd Seiger said: "Seeing this footage has sent shivers down my spine and made me feel sick. No harm done on this occasion fortunately but that is not the point.
"I have been urging everyone in authority to take the matter seriously, not only in terms of safety and how we can improve it in relation to helping American drivers adjust to the different side of the road, but also ensuring that no one who breaks the law coming off the base is allowed to hop on the next plane home and evade justice as Anne Sacoolas did.
"Enough is enough. This near miss brings both issues sharply into focus and I now call on the UK Government to take immediate action to ensure the safety of their citizens living in and around these bases but also to make sure that never again will a so-called 'diplomat' be allowed to evade justice.
"It is Team Harry's position that no one on these bases has diplomatic immunity notwithstanding the assertions from both the UK and US governments.
"I am in touch with Nick Adderley, Chief Constable of Northants Police, and Andrea Leadsom, our constituency MP in that respect.
"Preliminary discussions have already been held but Team Harry now expect these issues to be taken seriously and addressed now, and I call on the authorities to make a public statement to assure the nation that it will not be acceptable for the Americans to come over, injure us and just flee.
"Harry's parents want, more than anything else, for this to never happen to a family again, and I look forward to entering into talks with the authorities, on both sides of the Atlantic, to make it never does."
