Classic low savate kick, used (wearing strong shoes) to keep the attacker at bay, while avoiding being hit.
The left arm is bent and able to cover the face, or be used in a reverse (backhand) elbow, chop or hammerfist as the kicking foot is put down (for street kicking, I personally would want to make the leg 'heavy' straight after delivery, and get the foot straight back on the floor, without bringing it back. This is to guard against the leg being caught, to protect against a forward charge and also to avoid wasting time. Kicking and kneeing this way is much safer in terms of staying on our feet and much quicker to shift between arm and foot blows. To employ this, we need to be able to hit and kick from all 'stances' and positions, in all directions. Note that this kind of movement is quite different to that of normal, one-on-one sparring, and should be practiced with hanging bags or people holding pads and shields, practiced and visualised/imagined using everday objects (trees, lamposts etc.) and members of the public as 'attackers'. My next step is to add some pressure with 2 and 3 on 1 sparring and padded assailant scenario work).
As the kick comes down, the rear (in this case, right) arm can also be used for a straight punch/palm-heel or elbow, depending on necessity.
Practice keeping the head and feet mobile, keeping the chin tucked and looking up 'through' your eyebrows, and use shoulders, arms and elbows to guard against (possibly unseen) blows.
Be aware of your periphary as much as is possible (scan), and strike out at any suspected hostiles with the most appropriate tool to the most appropriate target.

The framework of my striking methods are pretty straightforward and easy to assimilate and use:
At long range; punches/palms, hammerfists and feet in any and all directions needed.
At close range; elbows, headbutts, knees, gouging and biting.

Blending attack and defence; vicious blows with movement and covers, and always looking to ruthlessly press home any advantage, whether attacking or escaping, and knowing when to be 'light' and when to be 'heavy' on the feet are what it's all about.
Deceptiveness and controlling range and options is the ideal strategy- if you're not just running over (or from!) your opponent, or they're not just running over (or from!) you.
