With Miami possibly coming to the Formula 1 calendar, where would your dream street circuit be held?
Let us know and maybe even said pictures of your street circuit layout, via #bbcf1
Image source, .Some news from yesterday - Formula 1 has received "preliminary approval" from Miami for a Grand Prix to be held in the city from next year.
Miami's city officials voted unanimously on Thursday to enter formal negotiations with F1.
If the event comes off, it would be the first street race in the United States since a Grand Prix in Phoenix, Arizona in 1991.
The Miami event would be the second F1 race in the US, in addition to the Grand Prix in Austin, Texas.
Right, let's do this.
Second practice is under way.

Robert Kubica doing his media session. You may have seen in-car shots of him steering apparently using mostly one arm. Fascinating explanation about what he’s learned about driving since his accident. More later but he says “the outcome is probably the same or nearly the same”

Another pound in the "for sure" jar please, Robert.
First practice also saw the welcome return of Robert Kubica being involved in a grand prix weekend for the first time in almost eight years.
It wasn't exactly a dream return to the track as he struggled with balance in the Williams but did post a solid 1:21.510, 1.2s quicker than his team-mate Lance Stroll, who crashed out.
"It was a difficult session for us, with difficult balance," said Kubica. "I felt comfortable, although it is difficult to be comfortable in such a difficult balanced car to drive. I think I did what I was asked and I am happy with what I delivered.
"For sure, although the balance was difficult I think I managed to drive well."

Well it didn't go very well for Daniel Ricciardo as he slide off the track and into a wall midway through the session.
Must be frustrating times in the Red Bull garage - if their drivers are not crashing into each other they are still managing to find a way to damage the car by themselves...
