Sun burns on banana - Banana burns???

I went out with my family for some work and parked the car under direct sun as it was open ground and there is no shaded parking available. I carried some banana with me and left the remaining inside the car. After coming back 4 hours later, I found banana peels got burnt as above. For comparison, two bananas which I carried with me are shown adjacent. Only peels turned black and inside, fruit is good though some softening took place. Outside temperature was 40 degree Celsius. The window panes were kept about 0.5 inch down from the top instead of fully closing while leaving the car to allow escape of hot air. Still, the above incident took place. I do not know what will happen, if we sit for four hours in the car in those conditions. Atleast second degree burns!!! We have to give a thought about safety against sun exposure and sun stroke.
